Ok so previously I felt my question wasn’t not fully described, this incident happened a few week so ago but my anxiety is fully taking toll of me, as well as this since of corona I shouldnt go and get tested until it’s over. With my situation , my friend was wearing very tight underwear , after we went swimming i realised I forgot a spark change of underwear, so he allowed me to wear his. There was semen on it, and even though i think it was relatively dry the material was going in my *** hole. Can I still get transmitted stds from the dry ish fluids getting in my bum?? After I saw I immediately took it off , the exposure being around maybe less than 1 minute. He must of masterbaited before we went , I’m really mad at him now that he could of infected me, but is it possible and would it count as direct contact since the pants was making contact with a mucous membrane .
