The conversation between human and AI assistant.
Does masturbation cause a vicious cycle by reducing penis sensitivity, which makes one have to masturbate longer or harder to reach orgasm, which further reduces penis sensitivity?
Can excessive use of pornography affect penis sensitivity?
Excessive use of pornography can desensitize the brain to sexual stimuli, which may make it more difficult to become aroused with real-life partners. However, there is no direct link between pornography use and penis sensitivity.
