A lot of people here will say the age gap doesn't matter, but I'm not one of those. I'm troubled when I hear of a guy dating someone 20+ years younger.
First let me say that there is always the anecdotal case where an cross-generational relationship works great, yada yada.
But more often than not I see an older guy who knows there's no potential for a long term relationship (what common ground do you have?), but has no qualms about being Mr. Romantic, seducing a guy who's too young and naive to realize he's young and naive, until he gets a little action.
And that's probably all he's interested in.
You're a hot guy. There are a lot of guys who'd like to get with you. But for your own happiness, find a guy your own age that you can build a relationship with. Don't get used by a guy who's just looking to score. And think about this... by the time you were born, you could have already finished graduate school.
Yes, I'm a cynic.
