Hey ladies, My gf is having a lot of problems with me and my size. She says its always sore and she always in pain, and that I've been giving her UTI'S. I try to be gentle in bed, but I still hurt her. Any tips? She no longer wants to sleep with me cause of it. This really sucks. What can we do to help prevent UTI'S, the pain, and soreness? Any help is appreciated, thanks!
