Making a move

I want to make a move on my best friend and see where it goes but I don’t know how.

Me F(20) and my bsf a M also (20) I’ve been knowing him for about 4 years I never saw him as anything but recently I have started to see him differently, he’s not women orientated, very straight forward and just over all a sweet guy. Now this is the part where it’s complicated a couple days ago we talked about sleeping together no strings attached and I agreed, just to clarify I’ve had started seeing him differently before any of this and I’m very good at not getting attached when it comes to one night stands.

So we did it and it was good but after we quickly separated and that was that we had called later on that night but didn’t talk about it the most we said was “ it was good” or just comments as jokes. the next day nothing had changed and I’m fine with that but lately I’ve been curious to see where it goes like if I just start making more moves on him like being touchy, kissing , etc I’m just nervous to see what happens and I don’t know how to start it. We’re both awkward because I guess we’re scared to make each other uncomfortable but we know what we both like and don’t like and the only reason we slept together was because we had actually talked about it and planned it. I’m also scared to ruin the friendship idk if I should talk to him in person or just make a move?
