I've just tried nettles for the very first time and I must say how much I enjoyed it. I was very apprehensive to start with, got some clean surgical gloves from the first aid box, pulled my foreskin back and gently applied them to the gland, it tingled nicely so I applied more to the inside of my foreskin. No pain but a good sensation. After I'd had a good long wank, edging session, and eventually came, the after glow tingling is still there. Certainly something that I would recommend and will definitely be trying again.
