Forced Orgasm or the non control of sexual pleasure is something both men and women enjoy. They want someone to take away all control of pleasure. This is very wide spread desire it can be a simple thing of teasing each other over and over again. It can be working someone up right to the edge but not letting them complete their orgasm in order to build up the pleasure. The other end of this spectrum is tying someone down and being very forceful into making them orgasm on your terms not theirs. For men having a vibrator being used on their testicals can bring on an intense orgasm that is closer to the threshold of pain then pleasure. There are men that also enjoy prostate play which means stimulating the prostate until the man ejaculates. For the majority of men the prostate does not give the pleasurable orgasm that direct stimulation does. The feel of those ejaculations can leave a man feeling empty and craving that orgasm that he can not obtain through prostate stimulation. There are some men that say the orgasm they have through anal or prostate is far more intense and longer lasting then direct stimulation to the penis.
Women often enjoy having a vibrator applied to their clit or inserted. With the large selection of toys that are wireless these can worn out in public for some different types of stimulation at unusual settings. For some women just teasing with fingers is enough to keep her right at the edge without allowing her to completely orgasm. When she is worked up to the point that the person wants her to be at the orgasm can be very long lasting.
This is different then ruined orgasm in that at the end the person will be allowed to enjoy those sensations. These sessions can last a few minutes or it can go on for hours. You can bind someone down to where they can not move. A lot of women enjoy being held down and teased by a stronger person. It can also be a strong session of submission and control. A dominant person can just tell their submissive to lay still and the submissive must do as they are told. These sessions can be fun and sensual or strong and dominant. The variation is what makes it so much fun for so many people.
