Is it ok to stroke the glans when masturbating (with lube on)? because i am worried if i might be stroking off the sensitivity or something.

See answer : The head of the penis (glans), the rim of the glans, and the underside of the penis below glans (frenulum) are all rich in nerve endings and most sensitive/erogenous areas in most men. Masturbation and stroking these areas often result in maximal stimulation and pleasure. There is no danger or risk of damaging, removing or "stroking off" these sensitive areas with normal masturbation or lube use.
