A few weeks ago when we woke in the morning my partner told me that while I had been sleeping he had been kissing my bottom all over. He didn't say this in a threatening way, he just told me as if he had been doing something nice for me. I had no idea of this, I must point out that I had not been drinking the night before, I am sure I had not been drugged. I know that if a man has sexual intercourse or attempts it with a woman while she is asleep that is rape or sexual assault. I am feeling very confused now about what happened. At the time I thought nothing of it but now I am wondering about it. I feel a little stupid because a knowledge of consent in my job is a big thing and I assume my partner knows about such things because of his job too. I know that just because of his job that does not preclude him from sexual assault of course. In the past when it comes to sex he has always been very gentle and respectful but I have been doing some reading and found out that having sex with a sleeping partner is a fetish for some people. That makes a bit of sense because when we met he was not confident when it came to sex and not that experienced. We do not live together and have been together for 18 months. I have good friends but this is not something I want to discuss with them. Would like the perspective of more objective others to get some clarity on this please.
