Here's my
I started dating my girl when she was 17. I was 21. I never dated girls younger than me before, and when she told me her age, I almost dumped her on the spot. I didn't because she was way more mature that your average 17 yo, (explains why I fell for her I guess) so i gave it a shot.
And now, more than 5 years later, we're still together and boy, did she grow out to become one hot mama! DAYUM SHE'S FINE!!!
But if this relationship ends (god forbid) I'm not going under 21. It just doesn't feel right. (tight yes, right, no... in case some smartass is trying to be funny in the next post) Girls aged 18 should date guys no older than 23, 24.
But that's just me. If she's 18 it's legal. So if you fancy 18 year olds and you're like twice her age go ahead and knock yourself out. But make sure her family approves.....
