Okay...wow.

That's a really big piece of info to leave out.

In your original post I figured you were both in the same area and meeting up in person somewhat often, maybe even thinking about a FWB or poly situation. But you're both in different states.

My dude,you have options. Escorts, dating apps, bars, clubs, meetups...literally any number of ways of meeting other women in your area who can indulge your fetish.

And you should try those other things out because if you do tell your friend, you will most definitely nuke your friendship into oblivion.
