If you're careful there should be no long term effects from anal sex. You should though read up on it on the web as there are numerous articles on the subject. Of course there are certain precautions that should be taken. Your partner should wear a condom, this will protect against many of the germs that are in the anal canal. Note I said many but possible not all. Using a condom to protect against these germs will also help in the prevention and transmission of many but not all STDS. Use a generous amount of lube. Most importantly you need to learn to relax your sphincter muscle. This muscle is not use to invasion.
Even though your partner used a condom make sure you wash his penis and groin area with warm soapy water before having any other sexual acts. This will help prevent any germs from being transmitted from your anal canal to anywhere else on you or in you. [ adviceman49's advice column | Ask adviceman49 A Question ]

You also run the risk of things like hemorrhoids and anal fissures, but these are largely the result of poor lubrication. UTI's can occur for you and your partner, but aren't all that common. Incontinence is indeed possible in the long run, like any of these other issues are possible, but not likely. Since you go slow and use plenty of lube, you should be fine.
