Oh man, there are so many kinky things you can do by yourself!
If you’re pain curious or a full blown masochist, clothes pins are your friend. Explore different parts of your body with them, noting the variance in sensitivity levels. Put several in a row, and feel the intensity heighten. When you’re ready, nipples and genitals will provide some memorable experiences.
Want more? Try a clothespin ‘zipper’: cut a piece of string. Proceed to attach several clothespins in a row, catching the string as you do so. Imagine if your skin was clothing hanging on a clothesline; the string would be the clothes line itself. And the clothes pins would be . . . the clothes pins. For the finale, hold one end of the string and forcefully yank the whole line of clothes pins off. #yolo
Here are some options that don’t have to hurt:
-use a gag or a blindfold while masturbating.
-wear a pup hood and dog collar
-try urethral sounds, cock cages and ball stretchers
That should be enough to get you started. Don’t do anything I wouldn’t do!
