You're young and chances are you're hanging out with young people. Many haven't developed an interest or interests similar to yours at that age, so it doesn't surprise me that you haven't previously found it. But now you have, so you have cause to anticipate that. Good for you.
Sorry that this thread is so self involved, but I thought of something last night, and remembered I'd heard it before.
I met up with someone who was 16 years older than me, and we got on like a house on fire. The men I've best got on with, about 5, have all been at least 7 years older than me if not more... but I never really put two and two together until last night. The guy mentioned in this thread was the first in the chain, so, when I get back I suppose I'll have to see whether the spark was because he was the first older man I've ever spent a lot of time with, or whether it was really real.
Not that there's stuff WRONG with men my own age, I can have a laugh, but I find them slighly vacant and unengaged a lot of the time.
