I've had one partner. We started going out it high school. She actually pressured me into sex well before I was ready, but things were mostly normal. Sex is cool. But it was never the most important part of our relationship. Well, for a long time, it was essential to her, which was hard on me. But later it became less important. Non-sexual intimate things I found much more important.
Having sex did not really improve my self esteem though. Although I was in high school at the time, I'm pretty sure my self esteem would be higher now if I hadn't had sex. Given that she eventually stopped having sex with me and said I was ugly when she broke up with me after 8 years LMAO.
So not a virgin, but I'm absolutely terrified of sex now
