I'm still confused about the risks of fellatio. is it more risky to receive fellatio or to give fellatio? i received fellatio and did a negative 32 day cmia hiv test. and is cmia a laboratory test or a quick test like a rapid test?

Fellatio is nearly zero risk both giving and receiving. If the penile partner has HPV, the average risk of infection to his oral partner is around once for every 10,000 exposures (i.e. it could take 27 years before virus transmission happens). There has never been a proved case of HIV transmission oral to penis, with risk estimated at 1 in 20,000 (up to 55 years before transmission might happen).
