My boyfriend and I made out recently at my place after which he headed back home. After he reached his house which is like 15mins away he tells me that his balls are paining badly. He is my first boyfriend and I don't have any idea why it is happening. He said he'd drink lots of water and will leave "them" free ( as in not put on his underwear ) that night so as to ease the pain.
Why did his balls hurt ?
And what has water got to do with easing the pain down there ?
He was horny from making out and needed to have an orgasm to relieve the tension and calm himself down. Lots of guys say it hurts to get really turned on and then not have an orgasm and they call it blue balls. I myself personally have never felt physical pain from getting turned on and not having an orgasm but I admit it's very frustrating and I feel anxious and can't stop thinking about sex until I have an orgasm if that happens.
Well, when a man is completely aroused but doesn't ejaculate, he starts feeling pain in his testicles during and after he loses his erection. A slang for this is "blue balls". (here's a link to the Urbandictionary definitions for "blue balls")
