I've been reading up on men and their natural tendencies, especially after recently discovering my boyfriend's secret porn and Instagram accounts. I'm trying to understand male sexuality and how it coexists within a committed relationship.

From what l've learned, it seems men naturally crave sexual variety and are hardwired to be attracted to multiple women, regardless of their love or commitment to their partner. I've come to terms with the idea that a man's fantasies often don't involve his partner and that his sexual urges aren't a reflection of how he feels about me. I know my boyfriend finds me very attractive and loves me deeply, but I also understand that no single woman can fully satisfy a man's need for variety.

That said, I'm struggling with where to draw the line. For example, my boyfriend has an Instagram account where he follows sexy women and saves lewd images. When asked why he doesn't just watch regular porn, he explained that he likes looking at these pictures throughout the day to "get turned on" or because he finds it enjoyable. He told me he watches actual porn when he masturbates, but scrolling through Instagram is something he does more casually.

I'm trying to accept that men are visual creatures and that sexual variety through porn is natural. But I worry about how far this need for novelty can go. What if it escalates? What if it affects what happens between us in the bedroom or desensitizes him to real-life intimacy?

My boyfriend already struggles to orgasm during vaginal or anal sex. He can only finish from a blowjob or by using his hand, which he has conditioned himself to prefer through strong stimulation. He says this isn't a problem because I should appreciate that he "lasts long," but it makes me feel inadequate. I put in a lot of effort to please him, and while I'm happy to finish him off however he needs, I can't help but wish he could orgasm during sex with me. l also feel hurt when he denies being attracted to certain women (saying they're "ugly" without me even asking) but secretly follows their accounts and saves their pictures. I don't know if he's ashamed or just doesn't want me to know, but it feels deceptive. My question is: how can a man balance his natural urge for sexual variety with being satisfied by one woman? If men need variety to stay aroused, how do they continue to be sexually fulfilled in a long-term relationship? Don't they get bored eventually?

I want to give him the freedom to express his sexuality in a way that feels natural for him without imposing limits or making him feel judged. But I'm afraid his porn use and habits will lead to him preferring fantasy over reality-and me.

How do you ladies handle these challenges in your relationships? I would really appreciate some advice.
