I mostly lift after work at night so I usually don't get to edge before the gym. However, when I do edge prior to lifting, I seem to have great workouts. I feel into the workout, great mind body connection, and feel really horny, usually sporting a semi. I thought I was the only one who noticed or did this.
I'm not sure if the edging produces a testosterone spike, vibe, or pheromone release, but anecdotally, I've hooked up and dated 3 different girls after catching them checking me out, making eye contact, and smiling after the pre workout edging sessions. Of course, it could be coincidental, or my semi that caught there attention rather than a testosterone vibe.
