How do i proposition a friends with benefits with a guy and keep it quiet?

[justkickinit]

I am bi and still in the closet. I am a senior in high school and want to wait until I move out to come out. I got dumped recently anddontwant the drama. Butthere is this guyat school who I am 90% sure is gay andsingle. We aren'tfriends butI'mnice tohim whenI see him. We both are in the same physics class but don't talk all that much. If i were to set up rules like if there is attatchment, we break it off kind of stuff,wouldthat be okay? Part of the reason I am thinking a guy I barely know is so there isn't attatchment and if it goes south it isn't my best friend. How should I initiate a FWBand keepitquiet? I know people think he's really nice (which i see too) so I hope he can stay quiet. How should I approach him? Can you give me any ideas for rules for this FWB? I don't think I would have anal with him but probably making out and oraltype stuff. How should I try to become friends with someone who keeps to himself mostly? What do you think
