I've had this problem for a while. The head of my penis, when I've pulled the foreskin back, is just far far too sensitive for me to handle, so as I can't actually touch it to clean it because it's that uncomfortable. I am a virgin so it can't be any sort of STI etc. Does anyone know of a way to maybe reduce the over-sensitivity (I think that's what it is) because it seriously limits how often I can clean my penis. I end up not masturbating for weeks because I don't want to have to worry about washing it too thoroughly, I just expose the glands when I'm in the bath (the water falling in the shower is too sensitive) in a poor attempt to clean it.
I realise the dire need for hygiene, and I'm desperate for a solution.
