What is typical for him to last in bed?

I was somewhat promiscuous when I was in college, the guy I am with now is my 15th guy. All the others lasted about 10-20 mins. The guy I am with now last about an hour, he is only 22. is he not turned on by me or does he just have better control? What is typical for a guy to last or how long do you ( male) or your man ( female) last in bed as far as actual goes?
