hey, i like this site and i thought i would pass along some of my personal experiences. in the event that you would like a firmer erection and heightened sensitivity and a more intense orgasm i reccomend trying these products: yohimbe plus tribulus at amazing herbs.com and Viramax by Solaray (cant remember where i got it but its easy to search) both of these products work quite well and are fairly inexpensive, certainly in comparison to viagra. the only side effect i noticed was that they both tend to be a little speedy and can keep you up at night. my body adjusted to this very rapidly. Viramax is intended more of a tonic to be taken daily once in the MORNING. it has less yohimbe, the speedy herb, and wont keep you up as much. both herbs work almost all day and seem to take an hour or two to reach maximum levels. they also give a nice energy boost which i enjoy as much as the sexual benefits but do not seem to make me edgy or uptight. i do not know about the long term safety of yohimbe; i have heard conflicting reports. it can speed up your heart so be careful if you have heart problems. try it!!
