<human>: Give me a shortened version of the text

My SO and I have been dating for a long time, we've had a breakup once but we manage to stay together.  We have been sexual for 4 years now and I've talked to her about my sexuality in full, but she has told me very little outside of just physical motions.  

I've recently been telling her about how the lack of communication has made sex just feel repetitive, but she either refuses to talk about it or flat out denies having any fetishes, fantasies, or anything worth mentioning.

What should I do?  Am I wrong to want to know more about her if it makes her uncomfortable?  It's making me feel incredibly uncomfortable staying with her.
<bot>: SO doesn't want to communicate on sexuality/denies having any outside of just "normal sex," causing significant relationship strain for me
