Would this hurt: A girl jumps on a guys stomach?

He's a trained professional so he's not hurt by it, but I can tell you that it probably didn't feel great even for him to have someone jump on his stomach.  Our stomach or ab muscles are not built for that.

It's different for many guys. Not to be gross but it depends on how tight the girl is and how fast you're going. That's some ideas. If it's his first time ever then it might be a short time.

We used to do this in Karate.  We didn't jump from a chair, we just would jump from person to person, though.  It takes a lot of practice to get enough control over one's stomach muscles, but it is possible.  It takes a lot of concentration to keep them strong enough for the impact.  During our testing, we'd have to do this one kata where we'd be wailed upon by a black belt.  They'd hit our legs, arms, and stomach.  The way we practiced was with many situps, and then punching each other in the stomach.

Go with your instinct (the other girl).

Yes, it is possible.  It depends on the position of her neck at the time, if she was relaxed or if her neck muscles were tense, how hard he pulled her, etc.

First I thought it was when I got jumped (punched in stomach). But it might be when I had them jumped in return. ;)

yes. It wouldn't hurt. Because you are just asking her something harmless.

Yeah, but you might get popped for it. Make sure she isn't in the company of a big brutish boyfriend.\n\nThen again, she might take care of the issue herself. Watch that knee coming up as you hug her...

Hell Yeah!  Can you imagine how much fun it would be spinning that chick around in circles on top of you.  It`s one of my dreams.  Can you introduce me?

if you like him even a little give it a shot. What could it hurt?

I would beat her off. I know karate. If she kicked him in the junk, I'd just get someone to give him an ice bag. I'd only allow a guy to hit a girl (and vice versa) if she hit him first or was physically threatening him, so I'd be pretty annoyed that he wasn't doing anything about it.
