Not like the penis, anus does not have any of its own lubrication. So, it is compulsory to use lots of water based lubrication before attempting anal sex with your partner. This will reduce friction during penetration to protect the very thin anal tissue from tearing.
This will be reduced discomfort, retain the anal musculature preventing incontinence, and also helps prevent an STD from entering through the torn tissue.
When speaking of STD prevention, it is very advisable to have your partner use a heavily-lubed condom during anal sex. It is very important not to go directly from anal sex into the vagina or mouth unless you’ve changed condoms or completely cleaned yourself with soap and water. This is very much important to keep in the mind. There are certain bacteria which reside safely in the anus and colon, which can cause infection when moved into another orifice during your sexual activities.
It is rare but dangerous complication of anal sex is rupture of the rectum. It can be caused severe injury and result in a severe bacterial infection. The signs of an infections are diarrhea, fever and lower abdominal pain. The bacteria causing these symptoms such as Chlamydia, gonorrhea, lymphogranuloma venereum, shigella and herpes.
