I've been using injections until I tried tadalafil. I was having trouble with my erections lasting long enough. The shots often had me hard, andhard so long my prostate hurt; but the head often got numb so no orgasm for me pretty often. The tadalafil not only gets me hard, but I'm noticing stuff that hasn't happened since I was a teenager. Random semi's multiple times per day, and morning wood every morning. And HARD. Often harder than when I was a teenager. I literally feel like my peen thinks it's 15 again. And I don't suffer from shrinkage when I'm cold, and it's plumper all day every day.
