Red and Violet dots while stretching

Hey guys. So I’ve been doing stretches on and off for about 3 months. Been taking a lot of breaks due to not wanting to do them, no real reason.

So recently after taking a small break I’ve started doing them again, currently doing Simple manual stretches, and the BTC stretch.

I’ve noticed after I’m doing the BTC stretch, I’m getting weird red and violet dots on glans, and behind glans. Only after the BTC stretch, others are not giving me this.

I’m also warming up for 5-7 minutes in hot water.

Have any of you guys got this? I’ve heard little red dots with girth but I get them with hand stretches.

I can only guess you are doing these stretches with a partial erection such that when you grip your penis to do BTC the internal blood pressure in your glans go high enough to break capillaries in the glans. The same as gripping one end of a tubular balloon as the other end expands due to increased pressure.
