It is a big deal, bro. Penis hurts, veins are bigger. Glans is all red and Keratinization of the skin happened.
Beside I had a huge "donut efect" and now it disappeared, but something is still wrong with my foreskin.
It looks different than it used to and I think I lost sensation almost completely in glans or flaccid while sliding motion (up/down).
I had sex with my girlfriend and I had problems with erection, when I eventually made it hard I couldn't ejaculate...
Sex lasts for 1 hour and I didn't feel nothing. It's not normal.
When she blowed me instead of pleasure I felt pain...
So i am devastated. Penis pump is very dangerous....
