I don't know if this method already exists...
I started doing something lately when stretching that really makes me feel it afterwards. Basically I get about 5-10% erect, just a little blood in the weiner, and tuck it back behind my legs. Then I squeeze my legs together and hold for about a minute. This both puts a backwards stretching force on the penis but also compresses the blood in the shaft. Its like a stretch and a hold/clamp at the same time. If I reach back and feel my head it’s solid as a rock and when I let go I feel that burn in my ligs.
Anyway I just thought I’d share this with you all and if you try it lemme know what you think. Feedback = good!
