Promiscuous 21 year old girl

For as long as I can remember I’ve wanted to know about seggs and how it felt. I swear the youngest I could’ve been was 3. I gained consciousness kind of early. I can remember the apartment I lived in at 2. A diaper change, the smell of my bottle being made in the same apartment I was in at 2. I can remember glimpses of my 3rd and 4th birthday. This is a little rambling but it matters. I would h*mp my stuffed animals as young as that. I cannot remember where the stimulus came from for me to want to do something like that. My sexual urges never left though. Through childhood, adolescence, teen years, and now I’m an adult. While I was in highschool I was in a relationship with a guy that took my v at 14. He was my only body all throughout high school. We broke up when I went to college. After being tied down by a narcissistic psychopath for so long, I went a little ham once I got to college. My body count has shot up. I’ve heard worse numbers but I don’t like the fact that mine is higher than what I feel it should be. Every day I get random icks about my sexual past and me lacking self control when it comes to men and sex majority of the time. It doesn’t take much for me to give in but I feel terrible either immediately after or down the line. This literally haunts me and I’m afraid that if I ever be with somebody important that my sexual past will devour me. I’ve never caught anything to my knowledge, but I still feel bad about it all. Is there a way I can cope with what has already been done? An explanation could be bipolar disorder. My therapist diagnosed me with it but I haven’t taken further steps to explore it out of complete fear. Also I’m pretty high functioning.
