Ok, a bit youg but give DHEA a try, but please read up about it before you go on it as it can have some funny side effects with some people, this will boost you up all round your sexual levals, start low 25mg day and work it up to what you think is best for you, you can also back this up with Tribulus again it covers most of the same things, but DHEA is a hormon booster, they are both over the counter things to buy or you can get them from PP or amazon.
Your age would be a great help?
One of the doctor referred me Andriol Testocaps (2 capsule int he morning and 1 in the evening) for 3 months. Is it a steroid and having it for 3 months will going to have side / ill effects ?
Why not google the drugs and see what kind of side effects it will have on you and you body.
