Is there any particular food or edible product (ice cubes for example) that you have used during sex? I would put a fireball cinnamon candy in my mouth right before I suck a guy's cock and that extra warming sensation makes him shoot Niagara Falls down my throat. And a couple of guys have put those flat ice cubes, like those that you get from the Hardee's/Carl's Jr restaurants, right in my tight hole before fucking my brains out. It's an awesome feeling!

I have not tried that yet, but it sounds like something definitely worth trying!
