Oh my goodness, if we were geographically close, here is what I would say.

I do not consent to anything sexual.

I do consent for you to receive a full body male bear hug. I will also massage your shoulders and neck, and if you trust me. I would even sit close and brush your hair.

If we were in public with coffee platonically, we could hold hands.

When this was done and you went home. Let your mind go wild, but just so you know you have a male human friend who respects you and your humanity for all time.
