'Sup, /r/relationships, my gf and I are currently fighting about our sexual activities and I'm wondering if I am totally off base here.

My gf and I started going out two years ago. For the most part it has been good but a few months ago we sensed that the sex started to get stale. My gf (I'll call her Amber for the sake of this post) suggested that we change up our music choices and I agreed. She put together a new playlist that turned out to be 100% Maroon 5 and/or Adam Levine songs. Not gonna lie, I hate Adam Levine's voice and want to swing a golf club into his fucking nuts. The bigger issue, though, is that she has stated that she finds Levine really attractive and she has a few posters of him/the band. I feel like sex with this guy crooning to my girl in the background will be really weird.

I counter-suggested that we play something more gender neutral like Kenny G (stereotypical suggestion, but whatever) or something that was at least not a guy serenading my girl. Amber was resistant, though, and said that we should at least try her choice because changing the music was her idea in the first place. She also said that she doesn't like instrumental music in general or at least in a "sexual" way.

Am I insane here? Her idea just makes me uncomfortable for some reason.
<bot>: Gf only wants to play Adam Levine songs during sex; am I being the weird one for being uncomfortable with this?
