On your day off go and sit on a park bench where kids play. Any plans on PEing will get you arrested and a reputation for being a pervert. This will stop you touching your dick.
Or why not have good old fashioned wank or have sex? Or find someone to have sex with. Or read a book or ride a bike or cook a meal. Or come round to my house and paint my front room whilst I am at work… I’d really appreciate that.
Just remember that during the day off, your cock is recovering and helping you grow in the long term. Have a warm bath and see your flaccid swell up with pride. Or how about a few low level fowfers?
