That must be a psychological boost for you because CBD is not a vasoconstrictor. I’ve never applied it down there, but I’ve tried both the patches and cream for pain relief. Expensive experiment. It does absolutely nothing for me except irritation at the application spot. I gave the rest away.
This is true as CBD is a facilitator as in opening up the blood vessels. Also applying to your cock probably won't enhance your sensitivity because the penis does not absorb lotions, oils, and creams as well as say a vagina. If a man uses it for anal sex it will help relax and reduce discomfort in the rectum but for increasing sensitivity the use of it has not been proven with controlled testing. Taken internally CBD has been proven to reduce feelings of anxiety by interacting with CB1 receptors in the brain and throughout the body. From personal experience I know the use of the oil reduces my anxiety. As far as helping my erection I have not found it to enhance it. It does not promote a firmer erection as Viagra or Cialis does. Nor does it increase sensitivity.
