I always greet my date with a nonsexual hug and wish them well with a hug. As long as your clean and don't stink, there isn't really a way for you to go wrong with that. Its more intimate than a handshake, but offers a little contact for you both. Plus, every now and then you get a whiff of one of the best things ever--that fresh, just-shampoo'd woman's hair smell--without being a creep. Mmmmm .

Throwing the arm over the shoulder, unless is timed perfectly, just seems like a creep move like you'd see in the movies. Again, unless the timing is perfect, it seems like you're just waiting for the right time to put the moves on and women know this. Then again, showing initiative with confidence is sometimes a turnon for women. I'd play it safe until the comfort level for both parties goes up and not worry about how physical I should be. That will come in time with the right one.
