Is this balanitis?

Hello I first had a rush on my penis 9 months ago. It suddenly appeared, without any kind of sexual interaction. It eventually left, but 2 months ago it came back. I have some kind of a blister on my prepuce. Does anybody know if that is normal??

R, what age are you? Did you treat that ‘rash’ I think you mean with anything.
The problem with the term Balanitis is that it simply means irritation on the skin of the head or/and foreskin of the penis: it does not say anything about the cause or even a particularly way of treating it
If you are over 18 you can post images / photos on here of what the problem look like …
Have you noticed anything making the blister even worse … ?
