Long term effects of anal sex
Actually, there are none, other than a deeper and more satisfying sexual relationship. But that doesn’t stop people worrying, or others maliciously spreading false rumors about anal sex.
The idea certainly causes much anxiety, such as in this case:
Will having alot of anal sex cause problems for the woman later on in her life?
They have an excellent answer is this reply:
My wife just had her annual physical and I went with her. Specifically to discuss the fact that we started having anal sex since her last visit, and I wanted to make sure everything was OK.
After having anal sex 2-3 times a week for the last 9 months or so, including very vigorous and deep thrusting on my part, I can report that her doctor says her rectum and lower colon are in perfect health. Her doctor also said that anal sex is fine as long as plenty of lubrication is used. She also said that there are no studies that show any higher percentage of anal prolapse, loss of bowel control, etc., in people who receive anal sex than in people who don’t. Those maladies are a product of age and/or disease unrelated to anal intercourse.
The short answer, is to have as much anal sex as often as you’d like without any unnecessary worry about causes any harm.
