It all depends of my mood. Sometimes I do it for hours. So I go with "material" in this case. Wouldn't be able to do it otherwise. But for those times where it actually becomes a need, no mats neccessary
Hell, sometimes I don't even need imagination. Just the sensation can get me off. Or sometimes imagination, sometimes talking about it to someone, sometimes porn. Nothing's really an ALWAYS thing.
I've been in such a zen state of mind before that I was only focused on the feeling of an orgasm I wanted. I imagined the feeling I wanted, and then I made it come to fruition. It was a weird spur of the moment thing, it lasted maybe 1 minute in total where I was in the zone, and it's rare. But that sort of thing is possible.
You should run for President. lol I don't 'need' anything to stimulate me during masturbation except my mind most of the time. Certainly porn movies really don't do it for me unless I'm with a significant other while watching it.
I work with some pretty good looking women, plus my wife has friends I find attractive, and I find it to be more interesting to imagine different things they might do for me than it is to look at some picture of a woman I never met. Plus I think Victoria's Secret, porn, etc., do not give a realistic view of what a real woman is like. A real woman is not air brushed to perfection. In my imagination, I can play whatever game I want to with women I know and nobody knows the difference.
Is Penthouse out of business now? I hadn't heard. They used to be my favorite magazine too, such a shame.
To be quite honest, I was never really that turned only by porn mags & their blatantly posed shots - even as a horny teen, long before the internet, when writing things like 80085 on a state of the art pocket calculator was exceptionally risqué. Even now I find posed porn totally dull. The only ones I find arousing are the obvious home made movies - the real thing.
I can do it without something, but porn etc is fantastic for helping. My lady naked in front of me also masturbating is also a big turn on.
Don't have to, but how many men get to masturbate to a nude woman stranger? My wife was at a local nudist resort. Towards the end of the day, she went to the indoor pool. Another couple was there but they soon left. After a while, a guy whom she had noticed showing up wherever she went, showed up at the indoor pool and sat down on the edge of the pool. My wife knew he had been looking at her so she decided to swim around on her back so he could watch her. At some point, she noticed that he had one leg raised, and realized that he was slowly and gently stroking his penis. She swam over toward him, stopped swimming, and stood up in the waist high water and faced him from about ten feet away. She stood there watching him masturbate. He continued, as he must have realized that she was willing to provide him a real nude female to look at while he masturbated. After she came home, she said "I think I had an experience." She told me what happened. I asked her what the circumstances were and how she ended up standing in front of him, and she said that when she noticed what he was up to, she slyly headed over in front of him and stood up facing him, "showing him my tits so that he could look at them while he was masturbating." Finally, she decided to leave and walked toward the steps in his direction. He got into the pool, erection poking out of the water ever so slightly, which she purposely looked at so he see her looking, and as she and him were passing he she said she could see his load shooting up in the air. She just continued to walk by and didn't look back. She was done for the day, and headed home. So, my wife stood nude in front of a total stranger so he could masturbate while looking at her. She definitely liked it.
I like to look at topless pics of either my wife, or celebs that I find attractive. Not always though, as I prefer to remember experiences I've had in the past (I'm blessed with a photographic memory)
