For nightlife my favorite place is the Korsakoff.
There's a lot of great art in Amsterdam - but **** all that and go to the Cat Museum. Cat's are awesome. Unless you don't like cats, in which case you can go choke yourself on weed.
If you were lesbian I'd recommend a Bever shop, but you're not, so there's nothing there for you unless you are weirdly into hiking.
The red light district is quite small these days, it's worth a walk through just for the novelty of it.
When you see weird hot food dispensers in the street or a fast food bar, then get a cheesy thing. Cheesy things in breadcrumb are awesome. If you don't like cheese then you can go choke yourself on cat hair.
There's a 7-a-side womens rugby tournament on whilst you are there, so your odds of the woman you are hitting on turning out to be a big butch dyke are higher than ever.
You might also catch Europerv, if you like PVC.
