Some stretching questions...
1) Why some people stretch left, right, up, down? I stretch, 40x30s 2 on and 1 off. Straight stretch only. Is that good, or is there any better way to stretch? I’ve got some gains with this.
2)Why you need to warm your penis after the routine?
3)Why black spots appear after routine?
4)How stretching grows your penis?( I know it does).
I’m at 16-16,5max. Thanks! Oh and why I get different results when measuring from the top? When measuring from the right side I measure exactly same spot than from the top. All help is much appreciated.
