Viagra. A buddy of mine told me he would take one unbeknownst to his wife and after like 45 minutes of screwing her she would be like,"did you take a viagra,you asshole?" Hahaha. So I was married at the time,this was a LOOONG time ago,and I told my ex wife,hey,lets do one and see what happens. So I took a whole pill and then hopped in the shower. My cock was so hard I could have punched holes in the walls. Needless to say she was cool with it lol. But the following morning my dick was still hard when I was brushing my teeth. I was in my late 20s then and I haven't taken one since. But I will if need be when I no longer get a boner. TMI whatever
