I've read here and other pages that it helps with getting and maintaining an erection. How does it compare to Viagra? Or is it all BS marketing hype? Generally speaking, I don't need either but I don't pop a boner as quickly as I use to but strangely once I am hard it stays hard, even after cumming I stay hard for about 15 minutes!! Younger guys get hard instantly but go limp immediately after cumming but I don't. Anyone else like this?
