I agree with the above info too.

I think you need to set some boundaries with this friend. One being what pronoun you like to be called.
Second would be a boundary on touch. When is it ok & when is it not?
And another one on images that are being sent to you. No matter how you identify, it's not appropriate to send images like this to anyone....as a suggestion.
You deserve better! Respect yourself & ask for what you want.
