Why does my boyfriend's penis twitch?

Ok,I've never been with a guy before so I don't know if this is normal, but I'll be sitting with my boyfriend and he'll be hard and every so often his d*** will just move. It's weird and kinda gross? lol. And he also has a habit of grabbing his crotch when he's sitting down. I've seen other guys do this so I know its normal but I don't know it the penis twitching is normal.

  • All guys penises twitch when the organ is stimulated. This is a necessary function caused by muscle contractions. It’s easy to overlook if you are manually are orally stimulating him but his penis will be twitching every few seconds all the way to orgasm which produces a series of rhythmic contractions (or twitches) one after the other. It’s not gross or weird, it’s a perfectly normal natural thing :)

  • It can move out of extra excitement or sometimes it twitches with a guy's hear beat because all his blood flows through it with his heart beat. If you put your hand around it you'll be able to feel his pulse through it. Some girls like that.

    • Most of the time it looks like I'm grabbing my penis I'm really just checking to make sure my zipper is still up so people don't see it.lol. Otherwise it's because it moved into an uncomfortable position so bad I really need to move it and rarely it's because I have a boner and trying to hide it.

  • The twitch when hard is from the 'kegel' spasm. You get more of them as you get closer to orgasm.

    • but he's just sitting there

    • Its not from him moving his legs etc, its more the muscle you'd use to stop peeing. That muscle twitches as you get closer to orgasm. In fact, learning to prevent those twitches can help a lot with orgasm control.

    • why would he be getting close to orgasm when he's just sitting there

  • penis twitch?... that happens to me when its either growing or getting limp. However its not like its a big twitch or anything, I didn't think anyone would ever notice

  • it's normal. happens a lot.

    as for grabbing his crotch, he might try being more discreet, but several times a day a guy usually has to re-adjust. It can get uncomfortable, or pinched in clothing down there.

  • Totally normal.

  • It's normal... the penis fills with blood as it becomes more and more aroused. It's like a "pulse" as the blood moves through it.

  • probably cause it wants to be touched lol ;p

  • In answer to your questions, yes and yes, it is normal. Don't over think is package too much. ;)
