I am happy that I am not the only one having this pre cum discovery. I connected it with the feeling of arousal. When I first started wearing stealth, it made sense that I was semi erect It felt so good that without any outside stimulation of people, videos, fantasy, etc. I went into a bathroom stall and grabbed my stealth while on and easily ejaculated into the toilet. After a yr the stealth started to wear and the arousal now only happens by outside influence. I’ve developed a tolerance after a few yrs.
