I have tried V pills when ever I go to the DR with buddies on a Monger trip. usually not untill my 3rd day of the trip when I already had 3 or 4 diff chicas. What I discovered, si that i find it more difficult to cum. Yes I get a raging hardon, but I find that i have to work harder to actually reach an orgasm. i am in good shape for my age, but i wonder if this is the reason some guys who use them and in poor healt end up having heart attacks that we read about. When I finally do cum, I also realized that I stay hard afterwards for like 5 min. And a cpl times the girl would begin to blow me, and i would be ready again. But doubt i could cum again.
