I've been to PS a few times and I really agree with DCArtist. As superficial as it sounds you'll get much better advice on this particular request if you put as much about yourself as you want us to know, ie age, bod type, sexual level and sleaze factor you seek. PS is one of the few places that really does have something for everyone.
If you stay in downtown PS and tend to use all your energy straight down to your last reserves partying then you prob. won't need a car.
