I use both hands. My preference for coming to orgasm is in several stages at an unhurried, leisurely pace.
First is mental preparation. Imagination is so important to me. I think about things which arouse me.
Next I work on my bum (both hands). I stroke my shaved cheeks, play with my smooth hole, using a mirror. Sometimes I use a dildo.
Then I gently squeeze my testicles in my shaven bag. (left hand)
I follow this with gentle stroking of my penis shaft and playing with the veins at the base to reduce the outflow of blood and to make a harder erection (right). I flick my foreskin forwards and backwards over my glans. (right) I feel my semen swilling round my bollocks, up and down my prick ... I hold back and relax ... my semen returns to my testicle bag ... I play with my prick shaft and knob end (left).. I repeat this edging several times until I can no longer hold back. A burst of ecstasy comes throughout my body as I come to orgasm an ejaculate, often 3 or 4 times ... each squirt is followed by a slight relaxation, then I come again and again ...
Sometimes I can't go through all these stages: in fact, when I was younger, sometimes I would come to orgasm soon after stripping naked, without even touching myself.
