No and I'd prefer not to use any meds.
I tried 50mg of Viagra once. I hadn't eaten for a few hours before and I waited about an hour and 15 minutes after taking it to have sex. My erection was no different than normal and unfortunately I was not able to go a 2nd time.
On 2 occasions I had 36 hour Cilias, I don't remember the dose, and my erections were amazing. It felt like my dick was trying to push past the head and explode to new lengths. I was erect again within a few minutes after orgasm.
But yeah, I'd prefer to not use either unless my wife and I were attempting to have sex all night.
