Seeing my boyfriend tonight

So I’m going to be hanging out with a group of friends later today with my boyfriend. We have only been dating a month and I haven’t seen him in 2 weeks. I want to do something that will surprise him but I’m a bit shy. I just think I need to get out of my comfort zone and stop being a little bitch lol. When our friends aren’t looking should I kiss him ? And if I do kiss him do I just go for it ? Cuz normally I’ll ask “ hey can I kiss you” it’s not the most romantic was of kissing someone but at least I’m asking for their consent. So maybe I’ll just lean in ? Any tips or advise?
