1.5 months ago i had so sexual interaction with other men (i am male)
i had receptive oral sex (unprotected, but NO ejaculation) with two people (one guy who i did for <20 seconds, and another guy who is a friend and claims to have only given oral sex to another guy in the past. both claim to be STD-free)
i had insertive oral sex (unprotected) with 2 different men (twice each. both claimed to be STD-free as well)
this all occurred within a month's period in the US.
since the last incident
1 week after - sore throat, cough
4~6 weeks after - single painful small pea-sized lump in left armpit (hurts when i clench arm to side of body)...would disappear after a day, but would come back in other location in armpit. not sure if lymph node inflammation. i'm starting to think it's because of my antipersperant (Degree) stick, humid weather, and smoggy air...but again, not sure.
6 weeks - saw abrasion on bottom side of penis shaft. no bleeding or open sore, but worried it was a chancre. put neosporin on, and has not been casuing problems for the past 2 days....
please help, i beg anybody for their opinion. i am very anxious and afraid of HIV (mostly) and other STDs. I have yet to get checked, but i am out of the US and do not trust medical services where I am right now.
