Like Fluff when I've gone for older men it's usually been me pushing for them, I think that's the difference for me. I'm not opposed to dating older men, but I am opposed to those who go around searching/coming onto only younger women.
I still think it's similar to the dating men off mfc, I would never date a man on mfc who is looking for a date/trying to fuck me, I think we can all agree that's pretty creepy, but if the guy isn't looking for that, and then you come to him it's totally different. It just seems the same with most girls who end up dating older men, that they came onto the guy, not the other way around, and it's the same with dating on mfc.
I would date a man who enjoys/doesn't mind my age, but I would not date a man who's with me for my age. That's just incredibly shallow and just a bit creepy.
Also like several people mentioned, most 18-20 year olds are not very mature and annoying! Almost a year ago two of my best friends were 19 and very mature, when I was that age I was mature too so I foolishly let an 18 year old move in with me. Every night parties, tantrums, empty bottles of Lambrini scattered everywhere, but that's apparently the norm, how most teenagers act! It was the same when I went to uni, I was amazed with how people acted! I've got a hell of a lot of growing up to do, every year I can feel myself learning and changing, but I'm still not the norm and have grown up a lot faster than the majority of people my age. I personally don't know why anyone would put up with that crap if they had other options.
