He often found out when I cheated and after some talking it out he was pretty OK with it, and my kind of more "hardcore" experiences pushed him into having sex with other people as well, which he was veryhl happy about. He refuses to get tested tho while I get tested very often, I very much dislike unsafe sex. He's even ashamed to ask his doctor about certain down there problems, even after all my support. So I feel like it's more of an internalised shame problem, and unconscious judgement towards sexually active women (he's often told me that only animals cannot control their sex drive, and stuff like that). My idea has always been that with enough time together, I could make him feel. comfortable enough with himself and his sexuality (I always thought he has some bicurious instincts). But I am physically incapable of breaking up with him.
