I can understand your concerns,first of all I would have asked you if you are circumscribed or not and also is the foreskin or the glans
of penis involved or not,
It seems like you are having Irritant balanitis
. And people with the same problem do have recurrent problems like these. If such is the case then you are a candidate for a circumcision
.after the procedure the skin of the glans become thicker and the sebum secreted by the foreskin is no longer there and the problem can be solved gradually.
I hope that help you.
Thanks and all the best.
