I don’t need them since my erections are fine, but my doctors have prescribed them since I have HBP (not gonna turn them down) - so I will take them on occasion to spice things up. I have had scrips for Levitra (years ago) and Viagra (current) and currently take OTC liquid Tadalifil as part of my daily supplement intake.
Out of all of them, Levitra, by far, was the most potent and would stay in my system for days. It gave me VERY long lasting, VERY BIG erections that sometimes got close to being painful (when I say I was hard, I mean brick-busting hard; on a 10-scale they would be a 15). Experienced plenty of numbing with it and there were a few occasions where I came close to reaching that “4-hour erection” window. The only real downside (other than some mild discomfort from the hardness of the erection) was that it really stuffed me up and my head felt a little swimmy for a few hours. Almost like a low weed buzz.
Viagra, for me, has been good - I can’t recall the dose prescribed but whenI do ise it, I break the pill into quarters and one of those tend to do very well; affects last well into the next day and rarely have I experienced any numbing. No real side effects other than the occasional stuffy feeling.
The Tadalifil has proven to be solid but only in terms of aiding in my PE sessions. I can’t definitively say that it does anything for my erections since I don’t notice any difference when I don’t take it. However, It does keep my flaccid really flush during the day and helps maintain good erections during my pumping.
