When I was 19 I hooked up with a 29 year old.
Basically the whole age taboo went down like this:
Her: "I'm 29, that's too old for you."
Me: "You're right. That'd be like having sex with my grandma."
Her: "[laughs] I'm only 10 years older than you!"
Me: "When you put it that way... [resumed making out with her]"
Having sex with a girl who's older than you is better than not having sex, however you'd be better off sleeping with girls your own age.
