A partner pulling away from sex is one of the most painful experiences in a relationship, and it’s far more common than most people realize. Between 2010 and 2024, the share of young adults ages 18 to 29 who reported having no sex at all doubled, rising from 12% to 24%. Even among married couples, only about half report having sex weekly. Whatever is going on with your boyfriend, you’re not alone in facing this, and the cause is almost certainly more complicated than “he’s not attracted to you.”
It’s Probably Not About You
The most important thing to understand is that male desire doesn’t work the way pop culture suggests. The stereotype that men are always ready for sex creates a brutal expectation: if he’s not initiating, something must be wrong with you. In reality, men’s sex drives are affected by stress, health, medications, sleep, self-image, and mental health in exactly the same ways women’s are. A drop in sexual interest says very little about his attraction to you and a lot about what’s happening inside his body and mind.
Stress and Mental Health
Chronic stress is one of the most common libido killers. The body’s stress hormone system and its sex hormone system work in opposition to each other. When stress hormones are running high, they actively suppress testosterone production. This isn’t a subtle effect. A man dealing with work pressure, financial anxiety, family conflict, or any sustained source of stress can see his desire drop significantly without understanding why.
Depression deserves its own mention because it frequently shows up as sexual withdrawal before a man recognizes (or admits) he’s depressed. Loss of interest in sex is a core symptom of depression, alongside fatigue, difficulty concentrating, and emotional flatness. Men are also less likely to talk about these symptoms, so what you see from the outside may just look like rejection. If your boyfriend has also seemed more withdrawn, tired, or disconnected in other areas of his life, depression could be driving the change.
Performance Anxiety Creates a Vicious Cycle
Performance anxiety is remarkably common and deeply misunderstood. If your boyfriend has had even one experience where he couldn’t get or maintain an erection, or where he felt he didn’t perform well, that single event can spiral. The next time sex seems possible, instead of feeling desire, he feels dread. He’s stuck in his head, worrying about whether it will happen again, which makes it more likely to happen again.
Over time, this cycle leads to complete avoidance. As one Cleveland Clinic psychologist described it, a man can eventually lose interest in having sex entirely because it’s “just not worth the emotional toll.” He may not tell you any of this. He may not even fully understand it himself. What you experience is simply a partner who never initiates and deflects when you do.
Medical and Hormonal Causes
Low testosterone is a real medical condition, not just a late-night TV ad. Normal levels for adult men range from about 193 to 824 ng/dL, and levels naturally decline with age. But conditions like thyroid disorders, diabetes, chronic pain, heart disease, high blood pressure, and kidney disease can all suppress sex drive independently of testosterone.
Medications are another major factor that often gets overlooked. Antidepressants (especially SSRIs) are notorious for flattening sexual desire and making orgasm difficult or impossible. Blood pressure medications, antipsychotics, and even some hair loss treatments can have similar effects. If your boyfriend started a new medication in the months before the change, that’s worth exploring. Smoking suppresses testosterone directly, and heavy drinking disrupts desire as well.
The Chase-and-Retreat Pattern
There’s a relationship dynamic that can make this whole situation worse, and it’s worth recognizing because you may be caught in it without knowing. Therapists call it the pursuer-distancer pattern. One partner feels the disconnect and tries harder to close the gap: initiating more, asking what’s wrong, seeking reassurance. The other partner feels that increased pressure as overwhelming and pulls back further, seeking space. The more you pursue, the more he distances. The more he distances, the more you pursue.
This doesn’t mean you’re doing something wrong by wanting closeness. It means the dynamic itself has become self-reinforcing. Distancers under stress tend to shut down during emotional conversations, prefer time alone, and keep things surface-level. Pursuers, feeling that withdrawal, ramp up their efforts to connect, which the distancer experiences as pressure or even entrapment. The critical insight therapists emphasize: pursuing a distancer almost always produces more distancing, not less.
How to Talk About It
The conversation matters enormously, and timing matters almost as much as the words. Bring it up during a calm, neutral moment, not right after a rejected advance or during a fight. Frame it as something you want to work on together, not something he needs to explain or defend.
A good opening sounds something like: “I want to talk about something important to me. It’s about how we can stay close.” That framing signals partnership rather than accusation. Avoid “why won’t you” language, which puts him on the defensive immediately. Instead, share how you’re feeling: “I miss being physically close to you, and I want to understand what’s going on so we can figure it out together.”
After you share, ask him what his experience has been. “How has this felt for you?” or “What have you been thinking about this?” gives him room to open up without feeling interrogated. Be prepared for the possibility that he doesn’t fully know the answer. Many men dealing with low desire haven’t examined it closely because the topic carries so much shame. You may need to make this an ongoing conversation rather than a single sit-down. Checking in periodically about intimacy, sharing what’s working, and being honest when something isn’t builds a foundation over time.
Redefining What Intimacy Looks Like
If penetrative sex has become loaded with anxiety or avoidance, taking it off the table temporarily can actually help. This sounds counterintuitive, but removing the pressure around a specific act opens up space for other kinds of physical connection: extended kissing, massage, showering together, or simply more physical affection throughout the day. Curiosity works better than pressure. Something like “maybe we can experiment and see what feels good right now” invites exploration without performance expectations.
For men dealing with performance anxiety specifically, this approach can break the cycle. When there’s no expectation of an erection or a particular outcome, the anxiety that was blocking desire often fades on its own.
When Something Medical May Be Involved
If your boyfriend is also experiencing fatigue, weight changes, mood shifts, or difficulty with erections, a medical evaluation can rule out hormonal or physical causes. A primary care doctor can check testosterone levels and thyroid function through basic blood work. If those results point to a hormonal issue, an endocrinologist is typically the specialist best equipped to manage treatment. If the primary concern is erectile dysfunction specifically, a urologist is the usual next step.
If he’s on antidepressants or other medications that suppress desire, his prescriber can often adjust the dose or switch to an alternative with fewer sexual side effects. This is one of the most straightforward fixes, but it requires him to bring it up with his doctor, which many men avoid doing.
What You Can and Can’t Control
You can create the conditions for a good conversation. You can stop pursuing in ways that trigger more withdrawal. You can suggest he see a doctor. You can redefine intimacy in ways that reduce pressure. What you can’t do is diagnose the problem for him or fix it on his behalf. If he’s unwilling to talk about it, unwilling to see a doctor, or unwilling to engage with the issue at all, that’s important information about the relationship itself. A partner doesn’t have to want sex at the same frequency you do, but they do need to care that the disconnect is hurting you and be willing to work on it.
