years ago I had a wooden stepladder that I'd use to masturbate. I'd get on my knees, put my chest on the top step, and put magazines (later a laptop computer) on the floor in front of me. then I'd grease my right hand and start pumping my cock. it would take me a while to cum, but orgasms would be incredible. the ladder eventually became too rickety to use. :-( Later it would be on my back looking at magazines or the laptop atop my chest. Nowadays, it's in an office chair in front of my desktop.

Naked. Reclining on my bed or in a chair. Legs wide apart. Hands all over my cock, balls and nipples. In fact, just like I am now!

I love sitting on my couch naked, legs spread, holding my nuts while I stoke to porn on the laptop.

I enjoy being in bed, completely naked of course, on my hack with a few pillows behind my head. I switch hands continuously, using the other to hold my phone and watch porn, Chaterbate, Tumblr, Kik, etc... Then when I get ready to cum, I'll lay flat on my back, spread my legs wide, and pull my knees and legs up a deep back as far as I can. I found that letting blood flow from my legs to my cock makes the orgasm that much better.

Sitting at my workstation with dual monitors going;
one with a long video running,
the other with multiple slide shows playing.
A cock ring wrapped on the base of my shaft, my cock swollen and purple as I edge for an hour or so. To keep the edge going, I often have to break and resume again later.
