Read the Dr's forum archives in regards to test times Frog.
Unprotected oral sex both insertive or receptive carry a small but real risk of Hiv and STD transmission, so just for being extra sure and have less worries, buy flavored condoms for oral sex, and use water base lub for the anal sex, since your exposure is real you need a 3month test.
Good luck
condom splitting event you need to be tested at 3 months, getting a blow job no risk, giving a blow job with ejaculation has a low low risk.
