Your mental safety, your body, your mind, your right.
The thing is, if it isn't for you, you are free to feel how you want, when you want everyone else be damned.
The bigger message IMO is that a partner should learned to love and respect the boundaries and definitions of you in the way you feel best.

That may mean making sure she is comfortable and relaxed and making sure her needs are met 100%.
