A gorgeous boulder, with powerful and elegant moves. Ab Lounge is an obvious line on perfect rock.
Climb the sloper rail from left to right, starting on the decent holds at head height. Follow the line of least resistance, and finish in the notch up and right, maybe using the right arete.
The flow you get on this thing is incredible. A world class boulder.

Not strictly in the Fountain Red Area. This climb is on the Sex Boulder, which is near Fountain Red. Best to use the Fennel guide to find it. But I'll give you an outline: From Cowell on Hwy 7, take Cowell Rd (1204). Dirt road. 5 miles in, you'll see 1204C branching left. Take that, and park perhaps a quarter mile down in a little gravelly/rocky turnout on the right. Hike back half way, and look for a cairn leading downhill (on your left hiking back toward 1204). Steep downhill hiking, then sneak through the huge chimney between the boulders. You'll come out in a little area with Electralica (v5-6, 4 stars) on your left, and Ab Lounge on your right.

The landing is good, although not perfect. The zone is fairly big, and there's a subtle drop-off beneath the climb.
I worked this on my own for the first day with 2 pads, and it was scary throwing for the lip. When I came back with a friend and 3 pads, it felt much safer.
