Hey, did you know you can go into some REI stores and they have a rock climbing wall? You can also go to some rock climbing studios and they have rock climbing walls. You can also go to nature and nature has rocks you can climb.
Or you can go to some creepy storage closet or indoor alley deal and find a penis climbing wall like this. The difference is it's penises as handholds, which you should be used to.
Though only two penises won't get you up that high. You'll need way more than two penises to get where you need to go. But you knew that already.
