Twice broke a dom while in action, both times in BKK, girls seemes a bit annoyed.
Once in BKK LB slipped in during foreplay. After two pounds we both came to our senses and mentioned the dom at the same time (and we used it)
In Europe there was this girl I saw 4 or 5 times. Every time she insisted to use a dom and mentioned how all guys tried to get in without. The last time I saw her in the heat of the moment we started to fuck without and she was fine with that as long as I didn't come inside her.
Did have myself tested afterwards as as soon as the blood returned to my head I realized this wasn't the smart thing to do.
