(I'm 17, M) I went to a house party once out of town where I only knew one person, I met some pretty awesome people. We were around 15 people there. By the end of the night one guy had somehow hooked up with 2 and almost a 3rd girl and it wasn't even a secret, I asked him at some point what's his "secret" and he simply said "Just go for it, the worse thing that could happen is she will say no". I have no idea what dynamics they have as a group or if he was popular etc so I don't really know the background just that he manged to get with more than one girl over the course of a few hours.

That was a few months ago and I've been to a few house parties in town since but I can never just make a random move on a girl, I usually build it up over the course of some time etc. I was thinking about initiating something today at a house party but I guess I was scared of the other people's response and just got cold feet in general.

How do I get the courage to just kiss a girl at a party or whatever knowing that I might see her at school and people talk and shit. Is there something off with my mindset? Amy tips or advice you guys could give me?
