I actually just found out that my boyfriend/dom is younger than I am - he doesn't talk about his age, he runs his own business and most people would be reluctant to sign the kind of deals he's doing with someone only just out of their teens. He doesn't mention it, just lets people assume that he's older than he is.

He has more experience than I do, is certainly mature for his age, although being young and silly myself too much maturity is not on my list of qualifications.

I don't think I'd want to be with someone terribly much older than myself, I enjoy being silly and immature too much. I don't need someone much more experienced than I am, although much less would be more difficult, I'm a lousy teacher.
I don't want a dom to be my guide and teacher, I want a partner who I can explore this crazy world of kink with together. Someone more experienced, more mature, older, would make me feel like a student, not an equal in the relationship. And that's what I need, there may be a power dynamic in the relationship, but if I didn't feel that I was equal to my partner I wouldn't be happy in the relationship.

Also, I'm most likely shaping my current 'ideal' to fit the guy I'm with right now, because I'm completely head over heels like that.
