I have been having extreme issues since I was very young. I was molested. My sister and I were forced to do stuff together by some adult we don't remember. I don't remember this occurring but I remember that after she got put in jail and our parents went back to neglecting us we continued the behavior the whole way up to when we turned 12 we hit puberty early too. Her at 8 and me at 10. We are a year apart from each other. After our sexual relationship ended due to us realizing it was wrong as we didnt know  until then. I became addicted to porn. Fast forward to adulthood. Right after I lost my virginity I became super addicted to sex. My first girlfriend left because of it. Then I felt so much pain I slept around to get her off my mind. I had multiple one night stands and over the years it has just gotten worse and worse. At one point I knocked someone up. A few years ago I started posting on craiglist and having sex with complete strangers I would bring my friend along and we would double team these girls. It got bad but I went off the deep end with my sex addiction this past wednesday. I bought a membership to a swingers club and bought tickets to an orgy party. I had sex with at least 4 girls that night. A lot of them with other guys doing it with the same girl at the same time. I dont know what to do. The sexual stuff is part of my impulses when it comes to my BPD. ITS SO SCARY. I feel loved when I am having sex and it just feels amazing but then afterwards I am scared to death of getting an STD or of getting someone pregnant again. Idk how to stop anymore its like a huge coping mechanism when I start to feel hopeless about ever finding true love and leading a normal life.
