Actually, your tour isn't "bad" - just needs a couple more pages and tweaked up a bit. Where you show the 4 sample blocks - get some hot text working there as well. Use good keywords while you describe the hot action going on, and be sure to pull those into your meta tags as well ... will help in the SE spidering. Add a couple more sample vids into the center block so that the added text in the left and right columns ends up matching again when you're done.

Change the two graphic text blocks to left and right of the join arrow to read Members Login on left and More guys I tricked >> (or something similiar) to move them to at least one more tour page and put up another page of samples with some clips down the middle again.

Another thought - the big pic of the guy in a sample block - maybe have it pop a full size pic sample ... and just link the small pics to the join. Gives em some big pics as well as your sample vids in middle to see.

You aren't showing enough guys and working up the surfer or spelling out what all they get once inside to push them to the join. They need to see a LOT of your models - a join usually follows when they see someone they think is totally hot.
