I have been confining my husband to one position because I am having a lot of soreness in my groin from stretching ligaments. Also, since my belly is big, I can't stand for him to be on top and if I were on top, it would hurt my inner thighs. Any suggestions of great and safe sex positions?

We have been doing one where he is lying on his side and I am lying with my legs across him and my back on the bed.

It's going to be whatever is comfortable for you... :) As you go along, you will have to be creative, try different things, and see what works for both of you.
