Rodell Vereen, the South Carolina man who was convicted of having sex with a neighbor's horse, had better go to the doctor.

A recent study shows that men who have sex with animals are twice as likely to develop penile cancer.

Men who had sex with animals also reported a higher incidence of sexually transmitted diseases.

Of the 118 penile cancer patients, 45 percent reported having sex with animals, compared with 32 percent of healthy men, who visited the medical centers for benign conditions, check-ups or cancer prevention. Fifty-nine percent of men who had sex with animals did so for one to five years, while 21 percent continued the behavior, also known as zoophilia, for more than five years. The subjects reported a variety of frequencies for their sex acts, ranging from monthly to daily.

OK, that's just plain gross.
