Absolutely, I've posted before that as a versatile guy I top 99% of the time in anonymous situations but my partner fucks me bare and loads my ass quite often. We like to find a third, especially one that is versatile and I've taken multiple loads in one session and loved it. But for me I can't justify taking random loads like that. Am I aware of the risks I'm taking, absolutely. Do I want to pozzed, no. I have enough medical issues and no insurance so really not looking to add any to the mix.
Had a poz houseguest a few months ago, nice guy. My partner and I were trying to help him out of a bad situation. Long story short, his last night with us he and I were alone in the house. We got fucked up on synthetic marijuana and he started massaging me and that's when he started coming on to me, things like "let daddy give you the bug" etc, being that I'm not really into drugs next thing I knew, we were both undressed and he was rubbing his hard dick against me telling me he was gonna poz me and that I just needed to go with it. I freaked out, explained that while I was attracted to him ( and truth be told in my inebriated state I wanted him to fuck me) I couldn't knowing take his poz load, not just because I don't want to be pozzed but because I didn't want to risk exposing my partner to anything he didn't ask for.
