Getting Down with Extra Pounds: Fav Positions?

Darrah
This is a post for my friend who asked me to make a post because she was too shy to do it herself. I have two friends who I love to death, but both her and her boyfriend have recently been having some problems. Neither one has ever been super tiny, but both have gained considerably more weight lately and its effecting their sex lives. They are trying to get healthy again, but in the meantime...
Do you or your partner struggle with weight and sex? What's your favorite positions to overcome and still have hot sexy time? Help!
I've tried to suggest some things when she asks. Some work and some don't. But also I feel awkward trying to help since I'm the "skinny friend" 😕 so I'm opening it up to the community! Thanks lovelies
