How it's done: Start with your lover sitting on a chair. Facing him, lower yourself onto his erect penis until you're sitting on his lap. Wrap your arms and legs tightly around your partner. Then have him cradle your lower back and buttocks while he slowly stands up. If your man's been hitting the protein powder, he may even be strong enough to lift you up and down on his penis. But if he's hardly hunklike, you can make this position easier for him by having him prop your back up against a wall for support or resting your rear on a table.

Why you'll love it: The Reverse Piggyback lets you be totally submissive — just hang on and enjoy the ride. If you find this position hot but a little too heavy, try going weightless in water.
