I've been jerking it for years, (as any teenager) and recently I lost my virginity plus plenty extra. (I'm 17 btw)
I swear I would rather jerk off than go to the effort to fuck a girl. I think in the future I'll only get with a girl if she makes it super easy for me, because it's so not worth it when I can just jerk off. My experience was plenty good it just wasn't anything special.
I've always jerked off and thought to myself, fuck, I need to fuck a girl for a change, and when I did it I ended up having to jerk off to cum after like 3 hours of sex.
In conclusion, you shouldn't worry so much about sex and girls and go on with your life. There are so many more things that are way more fulfilling.
TLDR: Sex isn't that good.
