I love this site!
Ok some people aren't into anal stimulation, but it is amazing, so if you're into it try this.
I like to go into my bathroom, and kneel down so my feet are near my ass. Then I get plenty of lube, and put some on my hole and whatever I'm going to put in there. I usually use a toothbrush travel case, which works pretty well, but whatever you are using must be at least a foot long. So put it in between your ankles and point it toward your hole, then start jacking off, as you do move your body down and up which makes for great orgasms. I can't buy any sex toys, but a good alternative I've found is a common pool toy, called a toypedo. It's a torpedo-type toy that makes for a great dildo. It's kinda big though, so I wouldn't recommend it to beginners.
