... he's too big for me! So, the situation is that my FWB has a very large penis and he has inadvertently hurt me a couple of times during sex. I'm rather small down below and I'm perimenopausal and thus a bit dry to boot, so it's not a great combination to start with, but even without that he is still a lot larger than average and he says he's been dumped before over it so I don't want that to be the final outcome for us.
Basically, spontaneity/quickies are not possible because he needs to spend a lot of time on foreplay. I can orgasm through penetration but only if he can grind the base of his penis against me, so it doesn't work with him because he can't get all the way in. He can't really let go during sex because he might end up banging my cervix. And although he hasn't said so, I know it's frustrating for him to only be able to half-penetrate me.
He is really great in every other respect, skilled at oral etc, and I like him a lot as a friend. But I also prefer PIV sex to any other type and I just don't get off on oral or fingers in the same way.
I am honestly looking for advice on how I might be able to get around this without ending the relationship. I don't want to let it go or to hurt him, but also don't want to forego PIV. Are we just physically incompatible?
