Can intercourse with multiple partners cause roughness on the penis?
human
my boyfriend and i have sex maybe twice a month. He does masterbate maybe 2-3 times a week.  I do suspect some infidelity.  last night i did perform oral sex and felt that his penis felt abrasive only while performing oral.  Can this be from him having sex with another partner?  He states he is having no pain or irritation, but i felt the abrasiveness in my mouth..
