Someone mentioned a test booster, tribulus. There are other testosterone boosters on the market that you might want to try. GNC or other health food stores, vitamin shops, etc will carry them. I used some stuff in a black bottle, think it was black perl or something, forget the name. Make sure you follow the directions as at least some of them will advice taking it for 4 weeks and then taking a 2 week break, or some similar type of schedule. Then there are the prescription and over the counter hard on pills but they do not affect libido, only blood flow to the penis. The sex drive, horniness will not be impacted by them.
