Ive started edging recently but i wanna know if im causing any damage with the way i masterbate, i have to stimulate my penis to erection, im assuming this is normal after years of masterbating, but my foreskin is quite tight so it feels like im tuggin on my penis when im semi, does this cause any damage? i dont go mad, but it doesnt feel pleasureable, so my next question what lubes do people use for edging? and should i use porn to edge. Gonna start with edging then go from there. Thanks.
