How about I prepare to tell this girl about my fetish hoping that she will explore it with me?
Seriously?! What do you think her response will be?
I don't think she will be too willing, but I'll try to change her mind.
I can understand your concern. Revealing something about oneself can give you anxiety. It is good to prepare for all kinds of situations so you know what to expect from them.
I am getting very nervous about it . I am planning on doing it over a text.
It is good to prepare and worry about this sort of thing, because it is a big ask. I hope that things go well for you and that she says yes when you're ready.
