How to initiate FWB?

I have been wanting to talk to one of my friends about seeing if he’s interested in being friends with benefits. However, I’m not sure how to initiate this conversation. Do I just ask? Do I hint at it? I’m not super sure what to do lol.

For context- I think he would be up to it, all of the signs point to yes but I want to make sure he’s okay with it and set some boundaries and everything!!
