I was a virgin at 19 too, and lost it the same year. Fuck the trust and respect shit. Fucking the retarded girl from HS was the best thing I ever did. Understand that sex, relationships and women are a skill. You need practice if you ever wish to retain that one perfect woman of your dreams that you've been waiting for. Experience as many girls as you can. Just be safe: always wear a condom (and never leave it where they can get to it later), and you'll be fine. You're not a girl that's going to lose the ability to pair bond. You DO NOT want kids at 19. What you want is to work on yourself, lift, be successful, game women, chase your dreams. Fuck, there's too much to address here. Just read "The Rationale Male" by Rollo Tomassi. Everyone always talks about books that "changed their life", well no shit this one fundamentally changed mine.
