I have done the same but found it not exciting enough, so i got some ants under my foreskin en rolled it back and then tied it of with a string so that the ants couldn't get out anymore. They stung like crazy and kept on doing that for hours until I couldn't stand it anymore. Had a sore dick for days after that and i liked it!
I am going to a wood by where I live piles of wood ant mounds. Can’t wait to stick my cock and balls into one get them biting and stinging. Can’t wait.
