I know that exactly. I also have ED and I love nipple torture. Such a fantastic sensation. I alternate between light teasing and squeezing or clamping as hard as i can take. Wonderful. I guess we are bothe masachists! SM is terrfic!
This one really pulls the nipples and excites my cock. Learned it from "little georgie" who has retired from xham. I saw your hot vids and pics with clothespins.
I am going to practice your nipple orgasm technique. Love those leg spasm orgasms.
I've had them while being sucked and with estim. Now I will try with your method.
