I masturbated with a pizza
I hope you are joking? what were your thoughts?
"Thank God for this pizza and masturbation."
Did you do both at the same time? Using a pizza to masturbate may really hurt with all of the acidity in the sauce.
True, it was fun. It reminded me of scratching an itch, fulfilling.
While it is okay to experiment sexually in the privacy of your own house, pleasuring oneself with a pizza may be a cry for help and a waste of food. Have you considered speaking with a therapist about why this was done to try and figure things out?
