20 to 25 minutes for me. I've started waiting until closer to the appointment time before taking it. It seems the longer it's in my system the more difficulty I have achieving orgasm. Since I have begun waiting to take it I haven't had that issue. I haven't had an issue with being hard enough now that I take it regardless of the time factor. I'm going to try cutting it in half on my next session and see how that works.
Many men of all ages use ED drugs not only to stay hard longer but to withhold orgasm for as long as possible. I'm not sure if some call this a side affect or a benefit but I have noticed staying power from many of the gentlemen I see. While one drug may work for one person it doesn't for another so variety is a good thing. If you haven't found your perfect combination yet here's a new choice. If your looking for the next new pleasure drug it's worth reading about.

An older gentlemans need or desire to delay orgasm and maintain an erection. I've been getting complaints. Thank you Haley, you given me comfort that my "interest" can be accomadated by someone.
And I just got a few samples of Levitra from the doc.. It seems to work in less than the hour as directed. I guess another new drug that works even quicker would be great...
