I think that it's important that both partners be at the same level of emotional maturity. If your parner is too young, then they'll see being with you and "taking" you as a victory. Like they're fucking the president or something. They'll see being with you as winning a prize or stealing from the forbidden cookie jar. This isn't really so bad at first, but sometimes that kind of admiration for you just never wears off. They'll see you as being on a pedastel because you're older.

Now it is good to be adored, but I've found that long-term relationships work best if the two people view each other as equals. So, as long as they're not constantly introducing you to their friends and giving them looks like, "Yeah.. take a look at what I tapped last night! High five!", I'd say you'll do okay.

On the other hand, if you're just looking to get laid, and aren't aiming for long-term stability, then that power-dynamic can make the sex pretty fun.
