My gf (29F) thought it would be funny to play the song while we were about to have sex one time to see if I (30M) would get hard. Of course, she did this while giving me a blow job so, of course, I did get hard and then we proceeded to have the most amazing sex ever.

I thought it would be a one time funny thing but now she’s treating it like an experiment. Think Pavlov’s dogs: every time I’m horny, she gives me a blow job and plays the song. Her theory is that eventually I’ll just hear the song and get an erection. I love my girlfriend, and love how silly she is, but the last thing I want to listen to while we are having sex is four Australian men singing “yummy yummy” over and over again.

How do I get it to stop?
