How do you know when to kiss a guy?

oh man that's tough, i would just intensify the touching until you guys both slowly come to that point. you dint wanna do anything sudden CZ then you ll probably end up bumping heads or doing something awkward. make it clear that you want to kiss him, and i think things Will move pretty fluidly from that point

If he hasn't any hang ups like Hepatitis, lung diseases or ? then when your in a quiet place "stop and look at him, get as close as possible and put your hands around his neck/head and pull him slightly towards you, then pucker up and slowly kiss him gradually pressing a little tighter as you go" hold on as long as possible and then let go slowly. Ask him if he likes that, you tell him it was beautiful. Maybe he's been waiting for you ?
