I don't really know about Tantra outside of 20 or so article that I have read.  However, for the past 24 hours I have had a VERY NICE low intensity feeling of initial orgasm and it is INCREDIBLE!

I have been working out pretty hard again after a 9 month layoff due to a rotator cuff tear, and of course that drives my testosterone up.  I have also been having lotsa fun in the hobby and rekindling my joy of porno.  Well, I masterbated a few times on Saturday and never allowed myself to ejaculate.  I would always get really, really close then hold it back (I have good control and can stop urination on command).  Since Saturday evening I have had a nice buzz of an orgasm.  When I see a beautiful woman's website or read some of these replies it heightens this buzz.  It feels like the rumble right before the full intense feeling of orgasm and it is CONSTANT!

Question to other gentlemen...Have you had this feeling before?  Ladies or tantra experts...Is this just a small part of tantra?  If so, HELL sign me up 'cause this stuff is GREAT!
