LOL totally normal sounding. generally there will be a visual bulging near the vent, some of us call it "Sausage Butt" that is generally a good indication of a mess coming sometime soon. the more they are handled the more relaxed they get with it, some are curious and try to explore, others just hang out there with ya.
So did you ask your GF if it is truly better to be pissed off or to be pissed on?. LOL
