There are two typical issues that you may have, or perhaps a combination of things
You may have Balanoposthitis - often the issue is simply that you have a tight foreskin.
have you had issues of having difficulty in exposing your glans / head of your penis before … ?
no, never.
i don´t underdtand why i had this
now it is almost back to normal
Can you confirm your age? So if you are fully erect you are easily able to expose the head of your penis … ?
i m 40 yo
i can expose the head without problems
… does not seem to make sense, if you have had no foreskin retraction problems …
I have just grabbed this from a usually reliable source:
.
Inflammation has many possible causes, including irritation by environmental substances, physical trauma, and infection such as bacterial, viral, or fungal.
Some of these infections are sexually transmitted diseases.
It is less common among people who are circumcised as in many cases the foreskin contributes to the disease.
Both not enough cleaning and too much cleaning can cause problems.
.
I would therefore suggest if this returns, certainly, repeatedly, to go get checked by a Medical professional.
