I'm Asian, and I can hold it in throughout a weekend of action.
I disagree that it's just that they want to get it over with. I can go all night in my favorite position. And even in the rare event I climax, well, just clean up and keep on going. Why stop the sweet loving!
It's a bummer when people come to quickly, but I guess you could be a pollyanna and look at it as them being turned on by you.
Or you can ask them to do what I do if they don't want to climax too soon.
Masturbate 6-10 times a day, every day.
