Have watched videos on seduction but no comfortable with it. How do you come by doing it?

So I'm going to say in a party or social setting, not to gloat, but I kill game and amazing. But when it comes to one on one it becomes awkward at times and don't know how to use escalation tactics in that sense.

When there are a lot of people I'm able to be very touchy/feely and not care and it works. But it's that dang one on one...
