The problem was that the only place I really met undergrads was in my classes which I TAed or lectured. Because of the risks of the appearance of abusing a position of power I could never ask any of them out. If one would have asked ME out, I'd have done it right after grades were in. Unfortunately, girls don't tend to ask guys out in general, so that never happened. Bottom line, there's a LOT of risk for a grad student to ask out one of his students, but no real downside if an undergrad asks out a grad student.
Maturity has more to do with the individual then their physical age. I know 30 somethings that are less mature than some 18 year olds. For me personally I see myself more attracted to younger women for a number of reasons: For a guy I think that's okay, and I want to date quite a few women before settling down so I know I've explored my options before committing long term.
I would hate to rush into marriage and need a divorce. Girls that are around my age are past that point and are only looking for the one.
It's unfortunately not compatible with my needs. I need someone open minded, not so exhausted from past relationships. That just happens to be the case. I also figure, the girl will get older anyway, so if it's LT I'll get to experience her at different ages.
I spent my early to mid 20's working like some kind of 40 something, so I feel I need to go back and have the the fun I missed. I'm friends with plenty of people in their 20's, 30's and 40's of both sexes and get along with them great, but I feel undergrads are of most interest to me from a dating perspective of course I'll consider women that have already graduated as well, but my point is I feel more comfortable if they are younger.
I think a lot of my friends including guys and girls think this is perfectly normal but some are a little judgmental. I do have to say most girls my age are adamantly opposed to going to clubs or bars with lots of undergrads, but not all of them. I think it's a little unfortunate they feel that way.
Yes I feel some undergrads, especially the Freshman can be annoying but I can't fault anyone based solely on their age.
