I would take either, as long at they look good. I have like older women since like forever... I think I would draw the line at like 50 though.... I remember fantasizing about my teacher in 1st grade.... Messed around with a HOT fresman in college, and a senior when I was a sophomore in HS (did not look like it obviously)
They all potentially have drawbacks:
-18-early 20s does seem like too much drama even for a quick one, they will stalk you or something-too immature
-mid-twenties to thirties will try to marry you or get knocked up, don't let em get attached to ya
-can't see any drawbacks of the older ones really, as long as they look good...
any of you younger guys have some hot moms? j/k
