Dont know if this belongs in this forum, but a friend told me that when he was taking vitex (Chaste Berry) that it increased his sex drive/sexual stamina and now he takes it all the time. It got me wondering. What are some supplements that you people use for sexual purposes, be it stamina or just a libido enhancer. Ill start. I know its frowned upon and horrible for bodybuilding but any type of opiate be it hydrocodone oxycodone or many others, makes it hard for me to orgasm. So I can literally go for hours. (wish this was the case all the time lol)
