I've been seeing this girl for a year, when we first started hooking up she always told me to choke, slap, and pull her hair. I had no experience with this, but was up for trying and ended up really enjoying being dominant. After a few months she just sorta stopped begging me for it, and when I tried she just didn't seem turned on by it anymore. We still have great sex and she loves it, but when i ask her why she doesn't being choked anymore, she says her "sexuality's changed" and that it's normal for peoples sexual desires to change. I have a feeling it's because she somehow started viewing me as less of a man.
