So I finally bought a penis pump last night, and just have a few questions to see if Im doing it right. I pumped it until I felt pressure in my dick like when you have a very hard erection. I left it like this for about 15 to 20 mins then took a 5 min break and then did the same again, and if I lost the feeling id pump it 1 or 2 times more. The only thing that bothered me was I was a little sore today (but I figure thats normal with any work out), and it looks like my shaft is bent a little to the left which its never done. Did I over pump and hurt my self? Whats a recommended time and intensity for a new guy?
