And never do it again. Never self pleasure.

The long term benefits of retaining sexual energy far outweigh the short buzz you get jerking off.

Google 'benefits of celibacy'

Though celibacy in my case is being a single person choosing to no longer masturbate. Its been nearly a month now, and Im feeling excellent.. increased energy, alertness, motivation, focus, My dreams have been almost congratulating me on this, suggesting it is been a beneficial move. If not for the overt symbolism my dreams have shown, the fact that they have been more vivid is also a good sign. ive no doubt that not ejaculating and conserving sexual energy goes a long way in strenghtening the subtle body.
My music and martial arts practise also have utilsed this excess energy to enhance my performance. I encourage you all to experiement with this if you are on the path of self cultivation. Infact ejaculation for the old Taosists was a big NO NO, and Brahmacharya (celibacy) is one of the fundamentals of yoga.

Again Im speaking from a single persons perspective here, and am suggesting ONLY that masturbation and ejaculation should be avoided. If your already in a relationship, well its up to you weather to research it further.
