So I have been seeing someone for the past few months. It has been going pretty well, have taken things slowly (ish). We don't live together and both have our own places. I was staying at his house for a few days recently as we both had time off work and an "incident" when were in bed has really pissed me off so in the middle of sex he basically lets rip with a massive stinking fart and proceeds to laugh about it, not in an embarrassed "oh shit, I'm sorry" laugh but genuinely thinking it's funny and making stupid comments, it was so bad I basically had to open window and then take myself to the bathroom, needless to say the mood was over for me. Then he starts acting stupid "why are you upset, couldn't help it, dodgy food" and that I am being "up-tight". FFS we are mid 30s and he was giggling like a teenage boy would when in a group of mates.
So AIBU to think this was totally unacceptable? TBH I think it showed a lack of respect and hardly conducive to me wanting to shag him any time soon.
