I've known explicitly that my boyfriend is sexually submissive. We talked quite along time ago about the fact that I'm also submissive, and that I'd be unable to dominate him. He assured me he was fine with that, even saying that he'd be happy to take the dominant role in the bedroom himself. I understand I'm being utterly selfish and expecting too much. Admittedly I've just become more and more frustrated with his inability to do it. For example, he knows I'm into dirty talk, but he never seems to make an effort to engage in it. He says he enjoys the things he does do, but it but I find it hard to believe. I love him terribly and we have a wonderful relationship, but I'm worried due to us being so sexually incompatible - Will this ruin our relationship? Will the both of us become too sexually frustrated for it to work? I'm also worried that it's not normal for a man to be so adverse to taking control.
