i went to a massage parlor, when the lady came in she took off her clothes, and started to finger herself. she then grabbed my penis and started jerking me off with the same hand she was fingering herself with. she then put a condom on my penis and started giving me oral. i asked her to stop because i was scared of getting something from her. she took the condom off, got dressed and walked out of the room. is there any possible way i could get hiv from this? about months after this happened i had extreme amount of pain in my legs. this lasted for about a week. i have been feeling my arm pit and groin area so much looking for swollen lymph nodes that my groin and armpits are now actually tender. can some please give me some advise
