Play with pepper.
This is the worst sex tip Marin has ever seen. It came from a certain magazine, known for its unusual sex suggestions. "They seriously recommended sprinkling pepper under a guy's nose before his orgasm, with the thought that sneezing would intensify the orgasm!" says Marin. "I laughed so hard imagining someone keeping a little shaker of pepper by the bed and trying to get it right under the guy's nose at the exact right moment." This is flat-out the wrong way to spice up your relationship.
