Anything you want, and can feasably fit up there! Personally, I like to use a toy from "DOC JOHNSON" called "THE HAND" with plenty of lube!! But I haven't quite gotten round to asking my girlfriend if she'll do me in the ass with a strap-on. Just experiment.........and remember...........use lots of lube!
I did try getting myself off anal and it felt so fucking good when I cum. I never felt that good before.
Funny, because I don't do that stuff anymore. I once experimented with it twelve years ago when I was 28, but after doing things like that I lost the passion for it. Just feels like a toy is in my ass, so what. Then I stopped doing it. I love it when a girl shoves her tongue in it, but aside from that I don't care for much more than that.
I know what you mean, man. I've shot my cum all over my face before when jacking off with a toy in my ass. That sounds great. I've got to get me something like that.
Aneros Progasm - the most expensive lump of white plastic I've ever bought. While I haven't experienced their "whole body orgasm" thing (yet) as things go that you can stick in your ass its the best as it is specifically designed to stimulate the prostrate. The plastic is medical grade and very, very smooth and hard so nothing sticks to it when you rinse it off so it doesn't ever pick up any smell or "dirt".
