I'd never go out with an older girl.
In any case they expect too much, have more experience with relationships, think to much, go out too much, are too prioritised, and try to complicate many things that with a younger minded girl would be, simple..
Some people would probably say I'm not a mature minded person, but to me it seems logical enough that older women would be more difficult, harder to control and more difficult to compromise with.
All of this nonetheless is cancelled out with personality, and like other posts the situation. I'm so sure most guys are satisfied with sex in a relationship they could care less how old a girl is just as long as their getting a regular root. What's to complain about..
I'm assuming girls don't mind younger guys because they can keep them under control, and like younger girls are more naive, in any case.
