rough skin on penus

After a period of inactivity, say a little more than 2 weeks, I was having oral sex with my boyfriend. I noticed a rough line across the shaft of his penus just below the rim of the head. It was a thin line and went across the top. like he would see if he was looking down at himself. I did not feel it with my hand but with my lips and tongue. I was freaked out and did not ask about it. can you tell me what this could be.

Hi,

This could be allergic reactions to unknown substances, skin hypersensitivity, eczema,folliculitis, dermatitis or psoriasis.

He should try to keep the clean and use some powder to absorb the sweat.

Applying calamine lotion at the site would help. Does he have any other associated complaints like a rash, itching, burning sensation, etc?

Ask him to wear lose, comfortable clothes.

If the symptoms are still persistent, consult a dermatologist and get a proper clinical evaluation done. Discuss with the doctor whether steroid creams would be required.

Let us know if you have any doubts and keep us posted on how he is doing.

Good luck.
