Hi,
my meatus gets very swollen and red after masturbation. It is not very visible when it's erected, but the meatus changes its form into two big red lips. No secretion nor irritation while urinating!
I went to an urologist here in Italy, but he was very rude: that morning my meatus was ok, so he acted like I was crazy
I'm a virgin so I exclude any possible STD.
Urethritis implies having difficulties in peeing right? I have none.
