Well here’s the truth about keeping the “shroom” covered. Ian Kerner of goodinbed.com says that the foreskin contains very sensitive nerves that when pulled back and forth stimulates the frenulum. The frenulum is supposed to be the most sensitive part of the penis. It’s that part in front of the penis where your foreskin joins with the penis when you pull your foreskin back completely. A lot of women are still freaked out by the concept of keeping the sleeve, but that’s where you tell them that it’s a lot more stimulating to you and you’d prefer having enjoyable sex than the pleasure being diminished.
