I am a 19 year old guy and I have a question both about club etiquette and general advice. I have gone to nightclubs/pubs a few times with my friends and on the dance floor sometimes girls seem to stand very close to me and seem to be "inviting me" or waiting for me to make some kind of move (everyone tells me, and I suspect its true). Occasionally they even rub up against me with their bum and such. I usually try to escape or pretend it didn't happen because I just get TOO nervous. Later, I kick myself because half the time it's a girl I find attractive and would be interested in either getting to know or having some kind of frisky contact with on the dance floor. One of the things is I am terrified of moving badly or out of rhythm, of doing something awkward. My friends are all kinda fed up with me as I ask them about their encounters and seem to pass up any potential encounter I could have out of nerves or fear. They think I'm kinda 'living through them' by not doing anything myself. I'm also wondering about consent. If a girl dances up to me and rubs against me, that shows interest but isn't 100% consent, so how can I put my arms around her or dance close to her but ask? It's hard to ask because of loud music, maybe running away as I do is the best option.
