Cock Control
The art of cock control is more than just orgasm denial, although that is a aspect of cock control. John and I practice several forms of cock control.  At the beginning of John and my D/s relationship I honestly thought is all I had to do was to tell John don't masturbate, and that he would follow that rule because he is the one who wanted this type of a relationship. But I soon learn what many have already learned,  men masturbate if they have access to their dick.

Tease and Denial 
This involves the sexual stimulation of a person to cause intense arousal without climax.  I like to using this with edging, taking a man close to orgasm and then stopping contact to allow the erection to all but disappear before teasing again.

Total Denial with the use of a Chastity Belt
Chastity for me in my approach is that of sexual abstinence. I believe in controlling the mind and body.  I gain more  of your attention when I can control your orgasm.   For most, the use of a chastity belt is needed  for the wearer to surrender control over their sexual behavior.

CB-6000

Often referred to as the cage, because of the appearance of caging the penis.  Most devices are locked in with a padlock and the Dominant Master/Mistress would be the holder of the key to the padlock. The key holder would decide when the belt could be removed.

I have kept John in this type of device for up to 2 weeks with no real discomfort.  After 2 weeks I usually just remove the device, wash it, and then milk John's prostate and put him right back into the device. 

Another thing I enjoy with John is Tie and Tease. I love tie him down and teasing him.  I like tormenting him. I like to let him have his orgasm and then keep him tied down and continue the teasing. I can make him cum two or three times before he just wants to pass out.  They are intense and I love being that cruel.
 

I want to do a lot more with ruin orgasms.  I have a copy of sites that I found pretty good...
