My glans hurt when i masturbate. what can i use to fix this?

Sensitivity: A topical anesthetic such as Benzocaine should be plenty, or vary the ways and places in which you touch yourself.

Lubrication: You very well may need to add something to help lubricate the gland and penis during the friction caused by sexual activity. If there is a sore or infection a physician should probably determine the need for treatment.
