I masturbate to relax. To relieve stress. To release sexual arousal when I'm not with a partner. To keep my erection from becoming annoyingly sensitive.
Because I know my body and how it responds better than most partners and am able to bring about orgasms that are generally more intense than I get with a partner. Because it makes me happy to orgasm. Because its fun. Because it feels good. Because I cannot think of one single reason not to whenever I have the time.
Why on earth would any sane person deny themselves something so intrinsically human as an orgasm? Frankly, that sounds like insanity to me.
Because their ladies shut up shop
This has to be the dumbest question ever asked on this site. Why do women masturbate? There you just answered you own question. Next.......
Why do I jack off? Why do I jack off? I jack off because I get a boner even when not with my woman, and the only way to calm it down is to cum.
Rubbing your cock and letting your fantasies run wild is super fun and it cures boredom
I enjoy the feel of my hard cock in my hand. I enjoy shooting my load.
Pretty stupid question! Naturally, we masturbate to feel the erotic sensations of cumming ...and then to eat our sweet cum!
For the same reason women do,what a dumb question
After reading all of the responses, which would be my response as well, I would like it if cupcakemountain came in and explained a little further. It seems like we are missing something here.
Jill and I were walking once and her friend was up on an elephant. She was worried that he couldn't get down, so she asked me to help. Incidentally her friends name is Jack. So I w a s nice enough to help Jack off the elephant.
Many reasons. To keep myself lasting longer when the real presents itself, so I don't get awkward boners in the wrong place, boredom, horny, just for fun, or maybe to play out a fantasy in your head. Why DON'T you? If you can't yourself to an orgasm by yourself, it'll be harder when someone else is trying to get you there.
Because my co-worker wore that tiny skirt again. That's why I jerked off today at least.
if I don't ejaculate regularly my right testicle hurts because of DSBD. I also like to be able to keep my ejaculatory control high.
We jack off for the same reason women do. Sexual release
Mostly for the release. Not just the physical aspect, but the mental release as well. Then of course the obvious, because it just feels good.
Why?
What else can we do when there is no lady 2 do suck it? It gives us immense pleasure.
