because it involves your anus doesn't automatically make you gay
Anal masturbation is generally safe IF you use common sense, like not put anything up there or being careful not to scratch yourself (the tissues are delicate and easily bruise, causing infection!). I don't believe in giving info that encourages or promotes any type of sexual behavior, but for safety's sake, never use anything for a lube that you cannot pronounce (look at the ingredients, too!). Or, use anything that contains things that you might be able to pronounce, but know can sting or burn (like 'SD alcohol', etc.).Again, it's always important to use common sense, even if you're really, really curious.
