I've never felt the desire to slap myself in the plums with an elastic so it shall be a new experience. This could be my new thing, my very own weird kink. I could make it one of those griping points where I repeatedly start threads bemoaning the lack of enthusiasm shown by escorts when I present them with a bag of elastic bands.
Seriously though, I know what it feels like. I've had laser and IPL treatments. The IPL is much easier, doesn't bruise either.
