Go to the layby with the hogs back cafe on it , enter the woods just behind the layby starting from the cafe and heading to the right along a dirt path , you'll reach a small clearing hidden in some trees with bin liners tied to the trees. If no ones there just wait a few mins , at peak times they'll be guys in and out (mainly gay at least from what I've seen ) update : keep heading right to the end of the layby in the bushs , that's the main spot nowadays.
