I had unprotected sex with a girl 2 months ago, me and my new girlfriend due have sex a lot and sometimes can get rough but In past 3 months i have had two outbreaks of yellowish fluid like blister in clusters on my penile shaft. They sometimes itch, but do not hurt at all even when i touch, or burn when i pee. My first outbreak lasted 2 weeks and second just happend recently. Could these be friction blister or Molluscum Contagiosum?
