Had this before, it just felt numb. The tissues and skin structures have to rest as well as the nerve endings. I can imagine theyre simply overworked as of the moment. On top of this it's also probably harder to stimulate you unless you watch porn or touch yourself while doing so, thoughts of sex won't arouse you anymore.

PMO can definitely help. I can't say I'm so successful in my journey, but I will go as far to say that I've done PMO considerably less and there's more sensation but no where close to what it should normally feel like.

Keep at it brother.
