No problem its also good for harder erections and a slight increase in size, it also has a funny side effect, if we have really well developed pc muscles we can literally move our organ (because contracting the muscles pump blood very rapidly to it).
Also, i think that it helps to decrease the refractory period dramatically, so even if you ejaculate you can go on and on without loosing desire...
I didnt try with with a parter, im sure it would be a lot better though.
I tried to do it once again today, and i got to reach a couple of "waves", i didnt last long enough (to have a really poewrfull multiorgasm at least), maybe 4 or 5 times (maybe because i had a few normals orgasms before it), it was incredible, fiiiuuuuuuuuuuuuuuuu!, i feel veeery happy now and i cant avoid to smile (my skin feels very soft too, mhh), i think the more waves you ride, the powerfull the effect, i have to practice more, but it was quite nice, i got to admit though, that i tried to consciously do it before but i never quite understood how to do it, now that i reviewed it again and i understand it, i would never ever go back!, you should really try it!!!!.
