Thank you for the opportunity to help you with your question!
There are a number of health risks with anal sex, and
anal intercourse is the riskiest form of sexual activity for several
reasons, including the following:
The anus lacks the natural lubrication the vagina has. Penetration
can tear the tissue inside the anus, allowing bacteria and viruses to
enter the bloodstream. This can result in the spread of sexually
transmitted infections including HIV. Studies have suggested that anal exposure to HIV
poses 30 times more risk for the receptive partner than vaginal
exposure. Exposure to the human papillomavirus (HPV) may also lead to
the development of anal warts and anal cancer. Using lubricants can help some, but doesn't completely prevent tearing.
The tissue inside the anus is not as well protected as the skin outside the anus.
Our external tissue has layers of dead cells that serve as a protective
barrier against infection. The tissue inside the anus does not have
this natural protection, which leaves it vulnerable to tearing and the
spread of infection.
The anus was designed to hold in feces. The anus is
surrounded with a ring-like muscle, called the anal sphincter, which
tightens after we defecate. When the muscle is tight, anal penetration
can be painful and difficult. Repetitive anal sex may lead to weakening of the anal sphincter, making it difficult to hold in feces until you can get to the toilet. However, Kegel exercises to strengthen the sphincter may help prevent this problem or correct it.
The anus is full of bacteria. Even if both partners do
not have a sexually-transmitted infection or disease, bacteria normally
in the anus can potentially infect the giving partner. Practicing
vaginal sex after anal sex can also lead to vaginal and urinary tract infections.
Please let me know if you need any clarification. I'm always happy to answer your questions.
