I received a prescription for Bimix penile injection med from a urologist and I stay hard for hours (four to five). Yes, penile injection at the base of the penis. The needle is 1/2 long and ultra fine; if you go very slow it doesn't hurt much and I don't like needles and even I can do it.
I had to figure out the correct does based on my age, desire hardness and how long to stay hard; I use enough to keep me hard for four to five hour even after I cum.
I use Viagra at the same time to get the full girth going on.
Bimix will change your sex life and you'll feel like a God being able to stay hard for hours even after cumming.
Solid 8 (More like 9 or 10 I'm told).
