Additionally, sex is used as a weapon to control and manipulate. Additionally, BPD sufferers tend to use sex as a coping mechanism to numb the pain. BPD sufferers will choose destructive behaviors and do everything they can to avoid dealing with what is going on in their head.
I found this to be true with my uBPD. She admitted to me that she slept with various men throughout her life and specifically told me that she did it to ease the intense emotional pain that she felt inside. Most of the time she said it only briefly made her feel better and that she usually felt worse afterwards. According to her, she never used sex for that reason while we were together. She stated that she was only with me because she truly loved me. I'll never know if what she said was actually true, although I'd like to believe that she really meant those things.
