I'm not quite done experimenting but the recent evidence suggests that i'm one and done for any given day. Spent some time doing two a day appointments, and even with pharmaceutical enhancement, and though performance was sustained, I could not climax the second time.
Need to isolate if it was the second provider that didn't get me there, or my psyche that's to blame (I suspect a bit of both). I think an extended appointment with my favorite(s) is the next test. Of course, i'm just doing this for the sake of science.
It's been a fun, expensive week. 7 providers in 5 days. But, the pursuit of science is what drives me, not!
ATF's you are on notice that you are being drafted as future test subjects!
