Hello Texasgut
I'm reading your post on this subject. I'm a guy too that's fat and I masturbate myself every chance I get. I'll give you some advice from one guy to another guy : YOU ARE NEVER TOO BIG TO MASTURBATE !!!
I have met a few truly super-sized people (men and women >500 lbs) who could no longer masturbate in the traditional way, using their hands because they just couldn't reach. Having said that, there are devices you can use to help in that area.
