The general consensus on this sub is "eww, no, age difference is bad".

In most of the cases, they are right: a 45 year old man in a steady relationship with a 21 year old girl and poof, he gets manipulative and controlling. Yeah, that's most of the cases.

But I'll go against the grain (and I know it will be downvoted, so do with my advice as you please.) Personally, I guess it depends on what you want out of the relationship. If you have a thing for older men and want some fun, there is nothing wrong about getting it (as long as you're not leading anyone on about your true intentions). In the long run, these things usually don't work out. If you were 38, you wouldn't be with a 20 year old guy and expect to get married and have kids. Neither does this guy, all he probably wants is a young thing to have fun with, too. And that's fine, really.

If it doesn't get abusive, manipulative or controlling, and you're happy for a while, I'd say "go for it". I did too, it was a good experience, nothing long-lasting, but I learned a lot from what I want and more importantly, don't want in a relationship.
