Because they are prone to more anal sex, which is not natural, there can be breakage of blood capillaries and related injuries due to friction. He and Morris said that none of these injuries or STDs are restricted to the gay community. Lutz said not to overdo anal sex. Lutz said the rectum is forgiving tissue, but if you force something into it you face the risk of fissures or fistulas. Fissures are crack in the lining of the rectum.
Fistulas are deep absesses to the lining of the anal canal.
Morris said that lubricants can make sex more comfortable when using condoms. Rico, an uncircumcised gay man, said he was performing anal sex without any lubrication when he felt a tug on his penis. When he withdrew he found that his foreskin was broken and bleeding. This summer he will undergo surgery to become circumcised. Fearing incidences like this, Rogers makes sure to avoid such dangers.
