What is "blue balls"?

when a guys hurts and gets no fun for the play time.

I guess you'd say it's just a term to describe how a guy feels when he's been teased to death by a girl but she wouldn't go far enough for him to cum. Like he had a HO way too long and then had to go home with his tail between his legs. lol! Some girls like to tease a guy until he gets an erection for a few minutes and then she suddenly stops. The result is that the guy will have "blue balls" and that makes girls laugh. .

Kinda like Steven08 said. but I think that it got "blue" from when if a guy stops right before he ejaculates. and just holds it. and . well stops then after like a few minutes the balls turn blue from the blood staying around the area too long. .

Well I'm no doctor by far. but they could give a better description than that.

Basically if you stop right before he finishes and he feels a little pain from doing that. that's called blue balls. even though sometimes there not actually blue at all.

Pretty much its when a girls torture the shit out of us with teasing and what not, making us think we are on the road to the land of milk and honey then when we are hard as missile she leaves us.with blue balls.yep true story haha

Yeah like Linds said, it's about getting a guy worked up thinking he's going to get sex and then no happy release for him, lol. You hear this terms a LOT more in high school because so many girls are worried about who to sleep with, when to sleep with them, why to do it, etc. You've got a lot of virgins (not a bad thing, I stayed a virgin through graduation) who are concerned about when to lose it and who to lose it too. Even once a girl has had sex in high school most are worried about getting a reputation or seeming "too easy" and guys hormones are going in mega overdrive so you get this real mismatch of super horny guys wanting sex constantly and girls who are a little overly concerned with NOT having sex and you get a whole lot of "blue balls", lol.

It's when you get a guy worked up/turned on, but you don't finish him off. It leaves a distinct painful feeling for the guy to deal with and he oftentimes has to masturbate to get rid of the feeling.
