Yo Troops,
Do a internet search on the phrase "how to have tantric sex". I don't know a whole lot about the specifics but it sounds a whole lot like what I've trained myself to do naturally.
One thing this practice teaches is how to experience the pleasureable muscle contractions, but without having to ejaculate. I taught myself how to do this before I actually knew it was a whole, legitimized sexual discipline. lol
I think the trick is to be in tune with your body and FEEL the feelings without allowing yourself to release "the liquid". I know it works because I do it. my max so far has been two hours of hardcore banging without coming.
Most girls DON'T need anything THIS long to satisfy them, but I've got to tell you, when you can pull THIS off, you'll be the guy she measures ALL the other guys by.
The only downside to this is that it can make a relationship ONE dimensional. If the girl in question is NOT into you holistically as a person, you run the risk of being considered a HUMAN DILDO by her. Some would say that this is a great problem to have, but there is a huge price you pay when you aspire to be thought of by the women in your life as a lot more than a "HIMBO". LOL
One other thing, the only times that I have been able to maintain an erection immediately after I've ejaculated is when I was with a woman that was SO freakin' hot to me that I couldn't wait to get back at it.
I believe it was a psychological thing. And I guess that proves the theory that sex is ALWAYS at least 90% mental.
Peace...one day.
