I've read a lot on this forum in regards to what I am curious about, but I wanted to ask for my own sake of clarity. If someone was pressing the head of their penis against my anus, when the presence of precum is unknown, is this a possibility of getting HIV if their status was positive? When I say pressing, I mean roughly, almost with the intention of insertion, but the most I believe happened was the head of his penis was pressing firmly against a (spread) opening of the anus. Also, if the roles were reversed and I was the one pressing my penis against the opening of an anus in the same manner, would this be regarded as an exposure? Little worried, and probably over thinking, but asking for a piece of mind. Thanks!
