Sure, you might last longer your first few times, but it's easy to control it if you know what you're doing.
And only about 30% of women can actually orgasm from penetration, the rest need some other stimulation, so it doesn't matter how long you can last for 70% of women.
Well my many more years of experience trumps yours. Go and find out yourself... show it around and see what response you get then come back and tell us.
In the end- who really cares? If the girl you are with is OK with it cut or uncut then you are all set.
