I read this thing online that said you need this thing called lube to masturbate so that you don't get a rash on your penis. Is that true? If it is then should I stop masturbating since I have no access to lube?
Some guys use lube and some don't if your circumcised lube may help.
I have seen posts where people just use their own spit.
Just don't use harsh things like soap or body wash that can irritate your skin.
Just check yourself for a rash if your getting sore then you might need to find something or take a bit of a break.
