For those of you that enjoy mild pain or would like to try it, u may like this method. I discovered it quite by accident: I was applying capsaicin to my wife's arthritic feet after which I washed my hands very thoroughly to wash off the medication. Later, when I was playing with my penis and balls, I began to have a burning sensation. I then broke off the contact and the mild pain went on for several minutes and which I found quite pleasant, although I have never been one to cause or enjoy pain as part of any sexual act. [Regarding capsaicin, it is, according to Wikipedia: the active component of chili peppers, which are plants belonging to the genus Capsicum. It is an irritant for mammals, including humans, and produces a sensation of burning in any tissue it comes in contact with.] There is much other information on the subject here if you'd care to look at it. I have repeated it many times over the period since my first exposure, and have developed this method:
First you have to purchase the Capsaicin, which comes in a tube. I apply a small amount of the creme on my left hand (since I masturbate with my right hand. Assuming this session might well end in a jack-off to ejaculation, I use a latex glove on my right hand so as not to over expose my privates to the medication.)
Using my gloved right hand, I spread the creme all over my left hand, and then I thoroughly wash my hands with soap and water, to remove almost all traces of the creme...none of it will be visible on your hand but rest assured there will be enuf of the med remaining to cause the desired reaction. At this point I like to lay in bed or in a recliner for maximum comfort. Cup and gently squeeze your privates for a short exposure. Keep track of the amount of time you use (one thousand one, one thousand two, etc) for your first exposure. Maybe 10 seconds, then remove your hand. Nothing will happen right away, but have patience...it will! The burning sensation will appear and slowly grow to its peak to a degree related to the amount of exposure. Then judge for yourself if there was too much burn or too little and adjust the exposure time accordingly. The one time I overdid it, I laid on the bed with a continuous grimace on my face,..waiting for the pain to subside (about 5 minutes), but I even enjoyed that! This is intended for men...if this gives you women any ideas, obviously you do not need me to tell you to proceed with extreme caution!
