[NSFW] Is it unusual that a males high sex drive remains as strong into his 30's as it was in his teens, without ever being curbed?

According to various sources it seems men on average hit their sexual peaks around their late teens while women hit theirs in their early thirties. I accept that this will vary from person to person.

But is it normal for a male to maintain this peak and desire for many years without being curbed, despite multiple and regular sexual experiences? To the point where he* (just as a curious and sex obsessed teenage boy would) finds it difficult to turn down spontaneous sexual opportunities that present themselves, even when in a relationship?

*Err… not me.
