LoL! I’d say no second date, mainly because you didn’t really like him to begin with. I think if you had been incredibly attracted to him and were having the best date of your life, a little fart (or a massive one) would not have tainted it enough to ask the question, “Should I?”
In all fairness to the opposite sex and in general, I come from a very umm…gassy family and sometimes they just can’t help it. (I’m adopted so I was spared lol…but for my DH, who has hirschbrungs disease - an intestinal disease - farting is a sign that his intestines are doing okay) Also, something kind of humorous, maybe to me, is the fact that I tend to burp out loud a lot…not in public, mind you, but amongst people who know me well. And I can be quite good at it. The first time my DH heard me belch, he was delighted…he was so attracted to the fact that I could do that and wasn’t grossed out by burping. “Better out than in” as my mom always says.
Btw, we’re not a mannerless family…these things do not happen in public :D.
