So A Few Months Ago I Went To Give My

So a few months ago I went to give my boyfriend of two years oral.. I noticed with my tongue for first time he had some I guess yu can call it dry skin under his penis head... But the dry skin was almost like scabs.. He went to clinic they said friction from rough sex or hair rubbing together.. Not sure not the latter of explanation.... But the dry skin started to peel off after I denied him Sex for a week but just last week while about to have Sex I notice red welt like patches in the same spot like healt scabs but being dark complexion the red patches stand out but they don't stick up when he had erection nor are they pus filled or hard or look like warts.. They just look like their growing new skin but I'm still worried should I be...please and thank yu for help and time
