Don't just start and stop at the penis to arouse your man. The penis is just the tip haha of the iceberg when it comes to sensation! Experiment with all the new places to find out which one will send your boy over the edge. If your guy has chest hair, you might as well play with it. The area is more sensitive than you think, and he'll love you running your fingers through it. Place your hand flat on their lower chest or belly and, keeping your palm on their skin, run it up their chest until you have a handful of hair. Tug, starting gently, says Kait Scalisi, sex educator and founder of PassionbyKait.
