20 weeks pregnant and been waking up during the night masterbating my boyfriend while we are both asleep?

Yes, it is. Those fantasies are ingrained long ago.

I wouldn't ask. I think it's best not to say anything about what he thinks of because he will either lie to make you happy or tell the truth and make you upset. (or there is the chance that he really only thinks of you) Like the other poster said, you could send pics.

You could have phone sex or webcam fun. You would have to trust him a lot to do any of that though. You can have an agreement surrounding porn.

(if you don't agree with it then he should respect that).
