Either she's a psychotic botch or you've cheated many times before to the point where she's incredibly paranoid. Whatever the case, if the situation doesn't get fixed soon, your relationship might deteriorate.

While she's sniffing it, stick it in her mouth and say "Suck it bitch!"

haha just like that song Smell Yo dick

ok then, either something has made her think that you cheat or she likes the smell of sweaty ball sack!!!

Either she is an insecure bitch or you've cheated before.

If she's going to go through all the trouble to annoy you over her stupid insecurities... she better be sucking some dick after shes done sniffing

thats like me.. she has a legit fear.. I think my gf cheats on me when she goes to the gym talking to 30 year old men

what else does she want a polygraph test? lhh

Give her a mushroom stamp on the forehead for approval!

To be even more certain, next time ask her to smell your butt hole. So she won't think you've switched teams because she drove you to it.
