Horse Squeeze 440, a weird indication

One important feeling after performing the horse squeeze is the tingling that i started to feel. i’m not really exactly sure what kind of an indication this is, but I immediately let go off my penis once I experienced this. I’ve read here on the forums that it’s your penis trying to force in new blood, and the oxygen recirculation is being cut off. correct me if I’m wrong..but isn’t this a bad sign for an untrained penis ? Maybe I should just stick to Ulis and the newbie routine, and when I get a little more experienced..add in the horse squeeze with clamping to compensate for girth. As of right now, just stick to stretching and jelqing ?
