@yababylol:
This is a subject I'm pretty curious about, as I've recently gotten pressure from a companion of mine to try bottoming for the first time, and it's not something I've ever had to worry about in the past, beyond what a normal non-receptive-anal-sex person in the world would have to think of. The thing that's always concerned me is that my … er ... "digestive" schedule doesn't seem to allow for the kind of spontaneity that I keep hearing about anecdotally. I've always had experiences where my bottom knows when and where something is going to happen, but I've never really probed too deeply into any (if at all) prep work went into the "before"s of that.
As far as I'm concerned, the idea of just going bottom's up for any guy and expecting to be CLEAN while not really being sure of what could happen ... that's the most worrisome part of the idea for me. If that's not graphic enough. 
I don't mind the idea of bottoming for the right guy and I intend to get some practice, though. Someone please educate me if I'm wrong to worry about this, haha.
Don't worry about people bragging about being spontaneous and not having to clean - notice how they don't really go into too much detail or it's a case of them being the top!
Don't be afraid to ask otherwise how would we know - there's no gay sex education in school and it will probably be a very long time indeed until such a thing becomes a reality unfortunately so we can only learn by helping each other out. The fact is there is NO spontaneity when it comes to anal sex, none at all. Anyone who says there is lying or is just too dim to realise that their partner is the one doing all the prep 
Fact is shit comes out of your asshole and whilst it isn't stored on the other side of your hole until it's ready to come out, you do not want anyone to be putting their tongue, fingers or dick up there unless you are 100% sure it's clean because the no.1 killer of the mood in sex is the presence or the whiff of shit, and if you're not 100% confident that you're clean you will not be able to enjoy yourself and let go fully having fun in the moment because that nag in your mind will be there.
Firstly, a lot of it is to do with diet. If you are passing soft but solid healthy stools that's half the battle won. FIBRE is key here. A bowl of Bran Flakes every morning for breakfast and in a week or two a lot of bowel movement issues will be cleared up. If you're a health freak maybe your body is perfect and when you douche sweet smelling rainbows fly out your ass. Great for you! For the rest of 99% of real humans, we had pizza or pasta or something else tasty for dinner last night so we're probably going to fart and shit sometime in the near future. Don't let people who say their ass is a marble palace make you feel less about yourself. I see many guys say they eat hardly anything at all the day before they are going to get fucked. I don't know about you but that doesn't sound fun to me I love cooking and eating, so cleaning is definately the next part.
Douching - either with a specific shower head nozel or a turkey baister type pippet, both you can buy online from adult stores work just fine. Use tepid water, warm but NOT hot. BODY TEMPERATURE. And don't use too much water at once, don't think firing up as much water as you can hold up there is the thing to do, it isn't because the further up it goes the more chance it can irritate stuff further up than a dick will ever go, and the stimulation from getting fucked later on can start things to move down. Just use enough water to clean out the lower part of your asshole, before the "U bend" (look at a diagram of the body for what I mean here). Do it several times until the water runs clear and you feel clean and nothing else wants to move, you know your own body. 
I also like to douche a little while before getting fucked (say an hour) because it gives time for your body to relax and return to a normal state, if anything else does get stimulated to come down the chute you have time to have another round of light douching/cleaning. Obviously if you know you're going to have some fun that night or the next day, don't go out for a curry or eat stuff you know can make your ass explode, that's common sense but you don't have to starve yourself or be on a macrobiotic diet in order to enjoy getting fucked.
Sorry if anyone is squimish about talk of shitting, it's not very sexy is it. Well it's a whole lot less sexy to strike oil whilst getting fucked than it is to read about it on a forum. Anyone who wants to fuck or be fucked should be honest enough to say this is my ass, I also shit out of it, it needs to be clean and here's how that happens.
