I dont think the age should be an issue either.... however their are alot of life lessons learned between 17 and 21... you just need to make sure that it would work.

However if you were my brother I'd smack the hell out of you for robbing the cradle. If she is in high school and you are not that is a HUGE difference in worlds. You need to take that into consideration.... also the fact that it's illegal to date anyone who is 17 in more areas.

I think age difference are fine, my boyfriend is 8 years older than I am and I love it! Just make sure you jive together
