I'm currently in college and sometimes run into difficult situations when escalating. Some parties that I go play music and have a relaxed atmosphere, but there are not people grinding/dancing. This presents a challenge, how do I move to hooking up with a girl or bring her back to my room when it's awkward to get that physical with her at the party? Any ideas or suggestions?

Dude, EVERY situation in that you´ll want to escalteate will be difficult. Why? Because of you´re fear of rejection. Don´t let you´re mind create an obstacle. Escalte.
