lol oh man, the turmoil of gay sex.... i for one find the smell/sight/feel of shit a 100% turnoff, especially since I don't use a condom (committed, monogomous relationship of 5 years, tested, etc...) and that bacteria cas cause an infection.
my man is really good about keeping clean, and all i need to do is ask "Good to go?" and he knows what it means. he's always honest if he's not good to go, which i appreciate.
but this one time, lol... oh my god... we had broken up for a year and incidentally it was better that we each got to experience (safe) sex with other people. when we got back together, our first sexual reconnections were oral and manual, and it wasn't until a week or so later that we got back into the SWING of things. i forget now if i even asked if he was good to go, but he was. not. lol i didn't even feel it i was so sexually excited (and emotionally. i had MISSED him!!) but as soon as the smell hit me, i pulled out and same as you, it was all the way up to my pubic bone, in my pubic hair, ugh... not on the sheets though, i think we saved them lol
i just remember being respectfully grossed out, running to the shower, and laughing it off later

it's not like it was a 1-night thing, if you can't laugh with your partner about this kinda stuff, who CAN you laugh ab it with? also, i'm a Top so I've never been the dirty one, but once when I was sick (and naked) i pooped on the bed a little, so he's seen ME in some embarassing situations too I guess lol
oh my.
