Like now. With my laptop in a hotel.

My favorite place has to be in front of my computer viewing porn or showing off on cam for some close friends. I've masturbated in many different places over the years I'd have to say doing it outside in the open is a great feeling. The best way is to be totally naked. Even when I've done it at work I have to have my pants and underwear all the way off so I can really spread my legs and enjoy it. I absolutely love masturbating and know how to really enjoy it.

Either sitting in front of the computer or in bed with the duvet pulled back

Outdoors completely naked is great as well. Or skinny dipping. Jacked off on my back porchand in the pool many times.

I really love jacking off in hotel rooms while I am traveling on business. One day I'll find a like-minded guy that I am easy with and we will have a great mutual jack off session together. I have never found a guy yet that I was comfortable enough to try and initiate the mood, so I end up solo jacking.

I travel a lot on business, so I have some great jack off opportunities. On the road I cannot go to my favorite porn sites because I am on a company PC. Here is a description of one of my favorite hotel jacking sessions.

I get out my portable USB drive where I keep my porn collection. I usually choose a directory for the mood I am in. One of my favorite directories is called "Awesome" and contains pics and vids of curvy women with big tits for the most part. There are some pics of hard dicks getting a good workout too, and since I really enjoy precum, a few edging videos.

I lie down on the bed with my laptop at eye level propped up on a pillow. With my left hand I scroll through the pictures or videos, stopping on those that really turn me on. With my right hand, I stroke with a small circle made by my thumb and 1st finger -- lightly from just below the glans, to just above the head ridge. Usually in no time my dick starts leaking precum. Sometimes I dry off the first drops as I am still enjoying the dry and light stroking I mentioned above. Sometimes I will rub my precum on my lips and imagine that I am running my tongue across my jacking buddy's peehole.

Later after more precum is dripping down the head, I might start getting too close, and my precum starts to turn a little milky. At this point if I have not gone too far, I stop and let it throb. Then I dry off the head and start the process all over again. When I am ready to cum, I get to a particularly good picture (the good ones change depending on mood), then I focus on it while I increase the circle's pressure. Usually a lot of precum is flowing by now, so I let it drip as it will. When I get right to the edge, I stop and just let it "ease" over the top. Man this usually results in a mind-blowing cum!

Other then in bed I guess in the shower or in front of the bathroom mirror.

I live, as a nudist, on 14 acres in the country. Weather permitting, I sit nude on my deck and stroke myself for long periods of time.
Of course, it's always better if there's someone there to share it with.

Definitely in my car. I wear some loose shorts and bring some baby oil with me. I park at the movies on a crowded Friday night and stroke to the hot young tight bodies dressed like little sluts. I usually cum when I make eye contact with one.
