Possibly: The strains of bacteria that live in/around the anus are often much more virulent(=aggressive) than those that typically live in the mouth. Std's are also more easily transmitted this way (thinks hiv, warts, gonorrhea) as the mouth has less defenses than typical skin, allowing easier invasion by the bad bugs! plus, it causes awful halitosis:).
