Hey /r/relationships!!!! Hope you guys are awesome!!

I am flying home to visit my parents next week and I've been in contact with my ex-gf. To sum up a very long story it was a very toxic one year relationship emotionally and psychologically and she fucked me over royally and I did everything to try and make her happy. Her own friends even say that I was like a saint and her a piece of shit. We had a weird breakup.

Fast forward 5 years to today: I'm over the BS that she put me through, I live thousands of miles away, we're friends on positive speaking terms, and I've pretty much moved on with my life.

I let her know that I'll be in town and we got to talking and we are both currently single and she said that she definitely wants to hang out/party. I would REALLY like to have sex with her again b/c it was phenomenal (pretty much the only part of the relationship that we both enjoyed). I need advice on how to go about this. Should I be aggressive or let her make the first move? Any and all help is greatly appreciated. Thanks.
<bot>: How would you go about hooking up with an ex during a weekend of partying after which you will not see each other for a long time?
