The sensitivity of the hand is different than the vagina. The hand is courser than the walls of the vagina, as well as knowing just how to handle it with the hand over years of mstbting.
So with all of the jelging and pumping and hanging and mstrtbting the penis is used to a certain friction which the vagina doesn’t offer.
So I would bet money on if someone were to not do anything including mastrbting for let’s just say a month, the fireworks would set off real fast.
Masturbating, not mstbting or mastrbting, please.
