This is one subject I have not spent a great deal of time talking about. I guess that's because they are so easy to accomplish. But I have recently been asked what good a stifled orgasm is if the recipient still gets all “grumpy” afterwards. I have said that stifled orgasms are more like full orgasms than ruined orgasms. I stick by my assessment.
With a ruined orgasm, there is no drop, either physical or emotional, in the sexual arousal of the recipient. That is to say, he still wants sex and he can easily cum again. After all, none of the hormones or endorphins that accompany a full orgasm are released. However, they are released when an orgasm is stifled. That means, there will be a drop in sexual desire. The poor guy will go through all the same symptoms he would have had he been allowed to have a full orgasm. I have been told that the after effects don't usually last as long. At least in some men.
I am not a big fan of stifled orgasms except for their possible use as a punishment. Yes, a stifled orgasm can be a punishment. When the body goes through the normal ejaculation cycle, there is a great deal of pressure behind the ejaculation. When you stifle his orgasm, you are holding back his normal ejaculation, and all that pressure produced forces the semen into whatever area is available. Normally, it will back up into the bladder. While it is not in the least bit harmful, it can cause a certain amount of pain. Often twice. Once when the body is attempting to expel his ejaculate, and again when you release your grip on whatever part of his penis you used to stifle the orgasm. Of course, the pain associated with your release of his penis is not as intense as the initial backup, it is still a little bit painful. Or, I should say, can be. This doesn't happen to everyone, nor does it happen every time. It all depends on how long you maintain your grip.
Either way, the initial backup does, quite often, cause a certain amount of pain, and this is why I use it as a punishment. Personally, I love ruining an orgasm more than just about anything else. The expression on his face as he tries to produce a full orgasm when the stimulation is gone is priceless! The fact that he is still aroused and doesn't want to stop is key to keeping him in a “ready to serve” state.
Just for the record, if you intend on giving your man a stifled orgasm, its effectiveness is directly proportional to the length of time you hold it back. That is, the longer you maintain your grip, preventing any ejaculate from escaping, the more effective it is. If you release him too soon, because the pressure still remains, his semen may shoot out one time and dribble the rest. But if you hold him long enough, it will all dribble out. So it depends on you as to how long you want to hold him back. Sometimes it is fun to watch that first “blast” of semen come shooting out, knowing that he is not getting any enjoyment from it. But other times, you just want to watch his face when you finally release his penis and his cum just dribbles out.
So, yes, a stifled orgasm can be fun, just be careful of the after effects. Remember, he will experience a drop in arousal and desire for sexual activity if you stifle his orgasm. I think it is well worth the trouble to learn how to ruin his orgasms. Besides, it's fun practicing!
