A fair few years ago, I was with a really hot bloke from the Netherlands. Tall, dark haired and really good looking. He was also nicely endowed in more intimate areas.
We'd had sex a couple of times and were just learning what we both liked etc. Third occasion is in full swing, and he's on top. He pauses for a minute, and let's out a really loud fart which ordinarily wouldn't be an issue because they're funny. It was really nasty and we had to stop so I could open a window. Fortunately we weren't being loud.
We're getting back into things and I can tell he's getting close but he starts moaning really loudly because he's ALSO farting really loudly and is trying to hide it by moaning like a porn star, and then there's the fact that he can't hide the smell, and it hits me again and the over performative moaning/the actual farting, and the fact that the entire street must have heard him, meant I just couldn't do anything but laugh and gag.
Neither one of us finished and he was mortified. I couldn't stop giggling. It made him sulk. I couldn't help it.
Unfortunately, any sexual attraction I had, completely evaporated. Fortunately, his flight home was the next morning and I didn't have to spend days with him. We never met up again.
