Oral and anal, he did not ejaculate in my anus nor did I ejaculate in his. Also I did not ejaculate in his mouth, but he did ejaculate in my mouth, it was not much but he did. I have had head congestion, mild sore throat, joint pain, weight loss and constinence at about 4 weeks. He has had no sypmtoms. An antibody test result at 3-4 months is highly accurate.

How long you wait to get tested is up to you. No ejaculation in the rectum probably decreases, but in no way eliminates, the risk for infection when compared with ejaculation in the rectum. It is highly recommended that you use condoms for anal sex. Performing oral sex on a man is considered low-risk. You decrease your risk for infection in this case by not having your partner ejaculate in your mouth.
