I believe the basics to be the first steps in Qigong like for example - Awakening the Qi energy and opening the main energy channels. Learning how to collect energy in the belly and the basic taoism rituals.
I've been doing some Kegels for a few years and then I was lead to an article regarding the multi orgasmic male. I found out that I could have multiple orgasms if I stop the ejaculation with my PC muscles. For some reason at first I used to have from 3 to 5 orgasms, now I could only have 2 or 3 I have no idea why, still I haven't ejaculated for years and I like it. I'm 21 years old if that's relevant.
