Stretchers refer to cock rings that are meant to stretch either the scrotum, or can be used to have your genitals pushed further away from your body ( which can make you look bigger ) Lots of guys find this the most intense of erections. Cock Slings are both cock ring/ball stretcher in one, but using 2 rings ( or even 3 ) can be just as effective. Dividers literally separate your 2 balls away from each other for maximum engorgement.
