How can you avoid getting feces on your parter's penis during anal sex?

Well if you want to make sure, use an enema. Then have him wear a condom. If the female uses an ennema before it will take a lil while to clean everything out, like hours, and thats still no gaurentee that he wont get some on him. The colon is not supposed to store anything but there is a chance it has a lil bit left in it. My thoughts are, if he wants to go in the out door then he should be prepared to get a lil something on him, so have lots of lube ready and maybe even a box of baby wipes and a towel. Just remember there is a very slight chance to get preggo from unprotected anal sex, so you both need to be prepared. If you still do it without a condom dont wipe his and your stuff towards the vagina, as so you wont get stuff from the back mixed in with the vaginal stuff. Then you both should shower and clean everything really well to prevent infection in either of you.

Have your partner take an enema in preparations for your intimacies. Once the ole lower gastro-intestial tract is cleaned out, a man can then intert his penis without worry of fecal matter being deposited on it. Also use of a good lubricant as KY-Jelly will also help.

As suggested, use a condom. The only other alternative is to take a cleansing enema before, which will help but may not completely prevent feces on the penis.

An enema can help. Read this post. It tells you what you need to know about how to do anal sex the right way: http://mflife.wordpress.com/2006/10/12/anal-sex-101/

condom...or have them take a big dump before hand then get them to clean.

Don't avoid it... deliberately try to do it. That'll make the event even more memorable. I guarantee it.

Use a condom.

CONDOM. ive had a lot of buttsex. condoms are a must.

Another possibility: No normal meals 2 days before, just vegetable juice. A former girl friend did it like this, and it worked.

If you are not familiar with enemas, you can buy "ready to use enema" in a pharmacy or supermarket (in the laxative's isle), a popular brand is "Fleet enema"; also you have some local brands, they are unexpensive and will do the job.
There are some good sites on internet that will inform you with the diferent types of enemas as well as the equipment to be use.
Don't buy any equipment until you have a good idea on different sources, some sites will try to charge you 3 or 4 times the price of the same enema equipment that you can find in other stores.

it kinda goes with the territory. I wouldnt worry about it.

A condom is the only absolute way. If your partner is clean, and free of infections etc..then trace amounts of feces on your penis is not big deal. DO NOT insert your feces covered penis into her vagina....Very bad for causing serious infections..CLean it first before vaginal penetration.

assuming you are clean enough, you can use a condom but you should always clean after anal sex

You must allways use a condom. No alternatives.

C word and its not cock its condom or doush bag yourself f

There really isn't a method. I have anal sex with my girlfriend and I love her and respect her very much. Sometimes accidents happen, if a man is into anal sex and practices it a lot, then he should know this comes with the territory. She is beautiful and clean, and does her best to keep herself clean, however, anal sex is impromptu sometimes, that's what makes it more exciting. Posessing her "there" whenever I want to is what I enjoy about anal sex the most. If she feels she is not all the way clean there, she gives me a warning and from there she leaves it up to me, wether I want to continue or not. I NEVER turn it down :-) It's never out of this world messy. Sometimes it's even erotic to know she lets me take her however I want to.

The Big 'E'

Enema.

It can be a fun activity unto itself if done with the proper role play.
