Question

You can assess whether a partner is consenting to sexual activity through:

Answer 1

Body language, how they speak, where their eyes are moving to (if they are looking at you a certain way) and giving ACTUAL CONSENT.

Answer 2

Asking them, that’s the easiest way. If they are fighting you or telling you no that means they don’t want to do back off. There are quite a few indicators that someone doesn’t want to have sexual relations with you.
