Massaged my prostate for the first time last night and felt my breathing rate involuntarily increase as well as my heart rate (an alarming rate coupled with increased horniness). I had no doubt i was approaching an orgasm and have heard people describe it as a full body sensation. At the peak of this episode i began involuntarily twitching and shaking and it felt "good" but not like a traditional orgasm. It was just a period of 5-10 seconds of moderately more pleasure than the preceding process. Then the build up subsequently began to dissapate. I didnt feel any lasting "full body sensations" or PC muscle twitches or anything like that.

Was that it? Or am i doing something wrong?
