We’ve reblogged this illustration from Girlfriend and ExGirlfriend BDSM Gallery. They’ve got great taste in NSFW pics too.
This is a regular series of illustrated guides. You can find the others here.
I won’t go into the “why” of self spanking. There are many reasons it might be for you, and Thomas Salas’ article in the Further Reading below has an entire section devoted to it. Self spanking may sound easy to do, but many people report that it takes time to find implements and positions that work for you and lots of practice to overcome the psychological barriers so you can hit yourself really hard, time and time again. If it’s something that you want, then don’t be discouraged if it doesn’t work for you the first time. You’ll find your rhythm if you practice.
