I've only ever had relationships with girls same year as me or older but heres my little daft perception of age gaps.
I think that it's cool if all partys involved are genuinely happy with each other, its not a contest to see who can "pull" the oldest/youngest, thats just sick. For example, at my old school some guys I knew (who happened to be pikeys but I didn't hold that against them) told me how they'd gone out looking to see who could bed the youngest girl, they where 16 and managed to get from 12/14 year olds. Thats a bit sick and I think guys over 20 shouldn't mix with girls below 6th form/college (17+) because its just a bit weird and I think they should be able to get a woman their own age.
As I said I don't really know a lot about it but thats how I feel. Saying that I'm poo at relationships and get bored very quickly so longest is 6 months and I havn't had a girl friend since december (before that there was about a 2year gap)
