I am a gay man, and had unprotected insertive oral sex (my penis inside his mouth) with another gay man two months ago. I have read at multiple places in this forum that this is a low risk activity. However, this gay man I had sex with turns out to be HIV positive. He is also on medication, and is taking dilutegravir. The oral lasted for about ten minutes, and I did not ejaculate into his mouth. I am uncircumcised, and I am sure his saliva has come into contact with my glans penis, foreskin etc. because I was not wearing a condom. I don't what what his viral load is, or for how long he has been HIV positive. Should I get tested ? How probable is it that I might have got HIV ? Any help is deeply appreciated.
