Oh my god, PLEASE don't do this
This single event snowballed and ruined my life

I felt the same way from when I first got to college until I was about 22. I felt kind of like a loser and a little rejected because of the fact that I hadn't had sex, but when I finally had it at the right time, it ruined my life. And every day I wish it never happened that way.

What you're experiencing is probably an issue in self confidence. You want to be accepted in a certain way. Please talk to a professional and don't make the same mistake I made. He/she can help you feel better about yourself so you won't feel the need to make such a big mistake anymore.

And then I got what I wanted at 22
I even lied to the guy and claimed that I wasn't a virgin because I was ashamed that I was at 22

To make a long story short, after I had sex with him, I ended up "trapped" in an abusive relationship. By "trapped" I meant that I could have left, but I stayed even though I didn't like him or having sex with him, and he always pressured me.

I recognize that most cases like this won't be as extreme as mine was, but it will forever scar you.

I will reiterate:
See a therapist for self-confidence issues
