My BF wants permission to sleep with my sister
I just finished giving someone else advice her on loyalty and it reminded me (again) of a problem I have been having with my BF.
He is a great guy, we're steady, in fact I am about four months pregnant with his child. Thing is, for me, pregnancy is dangerous - at best. My doctors decided that is a very bad idea for us to have sex.
My BF and I were both non plussed over it, but for the well being of me and our child, we accepted it. We can still have oral and mutual masturbation and everything was fine.
So I Thought.
Lately though, my BF has been asking me how I would feel if he were to sleep with my sister, his point being that since we are twins it wouldn't really be cheating because she would look just like me and he'd be thinking of me the whole time.
I am Not buying it. It Still Feels like cheating to me, wrong somehow, and even if I went along, I am not sure my sis would be interested.
Whenever I complain about his saying things like this he backs off and tells me he was just kidding, but when we have "pretend sex" (As he calls it) he often brings it up.
Is this normal? I want him to be happy and sexually satisfied, but I am feeling a little hurt and conflicted.
