3ml. I asked if I could also take
Viagra. He said I could take 1/2
Viagra and 0.2. It worked but not for long enough. After 20 min or so of foreplay, it partly or totally disappears. I went up to 0.25 with the same result. I'm sure if I had gone right at it in the first 15 min or so it would have worked out well. However, we enjoy foreplay. My question is, would continuing to gradually raise the dose increase the time the erection would remain? I read that the starting dose for many is 0.
