I had unprotected anal sex recently and I now I am experiencing symptoms which include mucus, blood, constipation, BURNING but no visible signs around my anus. Two days afterward, I noticed my anus was sensitive to the touch, but that pain is gone now. My partner does have herpes on the lip, but not on the penis. These symptoms have been constant for a week. No ulcers or blisters. I alao have Psoriasis.
