How long do you last in bed with non-stop intercourse, no pausing.

I'm curious how long other men last. I was having a discussion with my mates about how I rub one out before seeing a girl so I can last longer. And some of my other mates dont need to do that. If I did that, I would nut instantly.

When guys talk about how long they last do they just mean from start to end of sex? Because I can take a 5 second pause when I feel like finishing and prolonged sex. Then I can last from 15 to 45 minutes, or whatever.

But when I watch porn the men are just non-stop pounding the girl and not finishing. I try to replicate that motion when I'm masturbating alone and it's impossible, I would finish if I continue. Let alone with a woman.

Are you guys able to just non-stop pound away and not finish? If so, is there something wrong with me?

Thanks!
