Are there any articles about different masturbation techniques for men

I've found trying different positions adds spice. A favourite is kneeling with my legs wide so it pulls my muscle taut. Also try using just your thumb and forefinger stroking lightly across the base of your penis head. Or a coarse cloth between your legs to tickle your scrotum, or tickling your penis head especially your nozzle with a feather as you masturbate.
