Is the prostrate muscle responsible for male orgasm?

Is the muscle that contracts during ejaculation the same muscle I need to master to have a "dry orgasm"?

• I read that the muscle I need to master is called the PC muscle, and that I can practice using it by stopping while urinating. Is this the same muscle that contracts when I come, the one I use to "pull my pooh upwards" while defecating, the one that lifts my penis upwards?

• Answer:

  yes sir....you gotta learn to target only that muscle...put a hand on your buttocks and abs to make sure thye are not helping... having a dry orgasm and being able to continue afterwards is not easy... every time I would try it, I would ejaculate inwards to my bladder and have a retrograde ejaculation, adn lose my erection...it felt like **** this guide has really helped to be able to do it now: http://www.mistermanpower.net/Multiple_Male_Orgasms.cfm
