Why does a good slap in the testicles make a male orgasim more intense.

You should try some "Tens" pads on your balls and on your S/O's pussy and tease eachother. Very Intense...

Hmmmm. I dont know about a slap(my hubby would just double up in pain if I did that to him!), but I do know that he enjoys my squeezing them as he approaches his orgasm. I have to be careful though, because on the odd occasion i've squeezed a bit too hard. When he's coming he doen't notice this, but when his orgasm has finished he curls up in agony which rather detracts from any pleasure he got from the orgasm!

it works. i slapped my guy's balls lighlty and he came straight away

Actually, a good smack to the balls usually ends the game for me, but that's probably why I don't normally go to the BDSM section of AB.

I love my wife to, and she loves to slap my boys durning forplay. She starts soft and gets harder as we both get horner. This can go on from 15 min. to a hour. Most of the time she'll get as hard as to make my knees buckle and at times She has hit hard enough for me to double up in pain (as funny as it sound this is pleasure for me also, I wished she'd do it more offen) this usually makes us both cum. At times she will tie them up so they so she can realy get after them. She has a leather strap that she uses on my but and the boys up between my legs. When we go camping we will take a walk an she'll sneak the leather along. When we find a semi private spot she'll have me drop my shorts and lean up against a tree and use the strap and at times her foot. We got caught by a woman once and the wife let the woman help out. I could go on and on but to answer your question
YES we both cum Very hard from doind this
YES I have been brused and swollen several times
But its still pleasureable
YES it is pain and pleasure
YES it can be use foe punshment or reward
Yes she did bring home a g/f from work and
and taught her how to do it
NO she didn't like it when I first had her do
it but now she/we are adicked

it add more strain to he prostate and it let it all go at once.

You see pain and pleasure are the basically same thing inside the nervous system, its you perception that makes it good or bad. My little man has learned to love a little pain with his orgasms.

It has the exact opposite effect on me. +4
