My DH wanted to sex thru the 1st pregnancy, but we couldn't as I had a low lying placenta and was advised to not have sex, so we pleasured each other in other ways.
This time, I am only 14 weeks, but DH himself decided to wait till about now, as I m/c'd last time, and he blames himself a bit as we were like rabbits. So he is now frustracted, but that will change, he is one of the few who still finds me attractive even with a bump, cause it means he get to be a lazy sh*t as me on top is one of the better positions, or dog, done very gently, again great for him. Also, I have HUGE boobs, which whilst there is no milk he is making the most of, in his words FANTASTIC.
There are som many men out there who find preg women attractive, I have some male colleagues who would just love to.
Try to speak to him and suggest gently positions like on top, or spoons or doggie, where he cant see the bump.
We waited till six months after as I had an episitomy, then the bloody condom broke and I had to go to the Doc's and be told off by the w*nker of a Doc like I was a teenager, so I had a go back saying we used condoms, but it spilt and I'm having the coil next week, he soon shut up. Just out bloody luck tho
