most helpful answer absolutely not. the air inside does not mean anything let alone proof of infidelity. the air is pushed inside by a smaller than average penis also some positions are much worse and i'm being serious here if you have a 7'' penis and better than average girth this will not happen.
does the vagina farting during sex mean that woman has been cheating? does the air inside come from previous sex? . my vagina makes that noise during sex every once in a while and my fiance swears im cheating but im not. i was hoping with medical personnel explaining to him that is a myth that he would stop accusing me of cheating.
