My husband has recently told me about a fantasy/kink he has where I wake him up by trying to have sex with him. We've been together for years and I've never had a clue about this so it's taken me by surprise and I'm not sure how I feel about it. At first it started off with him wanting me to masturbate him in his sleep to the point of climax which I have done a few times even though I felt uncomfortable about it (there's something about a completely unresponsive body that makes me feel weird about it) but now he'd like me to fully try to wake him up up by having sex with him.
I understand this is a kink and I don't think it's weird but I also don't feel that comfortable with it. Tbh sex has always been a bit of an issue with us (me not particularly wanting it as much as him) so I'm not sure if it's just that. He's not really pressuring me but I do also feel bad about not wanting to do it because he says things like he feels like a freak etc and that it's on his mind a lot. Even talking about it turns him on.
I just feel a bit lost. Is this something I should do even if I'm not fully comfortable with it?
