What do you think if I ask my girlfriend to quit smoking, even though she knows it's my kink.
How do you think she'll react?
She knows that I like it but she knows that I want her to quit.
Even thought it is something that you like, it is good to care about her health and want her to stop smoking. Now you can be together longer.
I know and it's awesome.
Good to hear you say that you want to stop a behavior, even though that behavior turns you on.
