Q how to do anal sex? does it creat any problem?

Anal sex is practiced by many heterosexuals, as well as homosexual couples. The anal area has many erotic nerve endings in both men and women. Because of this, many couples (heterosexual or homosexual) can derive pleasure from some form of bottom stimulation. Anal sex should be avoided by couples in which one of the partners has been diagnosed with an STI until the treatment has proven to be effective. In order to make anal sex safer, the couple must ensure that the anal area is clean and the bowel empty and the partner on whom anal penetration occurs should be able to relax. Regardless of whether anal penetration occurs by using a finger or the penis, the condom is the best barrier method to prevent transmission of STI. Since the rectum can be easily damaged, the use of lubricants is highly recommended even when penetration occurs by using the finger. Especially for beginners, using a condom on the finger is both a protection measure against STI and a lubricant source. Most condoms are lubricated and they allow less painful and easier penetration. Anal stimulation with a sex toy requires similar safety measures to anal penetration with a penis, in this case using a condom on the sex toy in a similar way. It is important that the man washes and cleans his penis after anal intercourse if he intends to penetrate the vagina. Bacteria from the rectum are easily transferred to the vagina, which may cause vaginal infections. When anal-oral cos ntact occurs, protection is required since this is a risky sexual behavior in which illnesses as Hepatitis A or STIs can be easily transmitted, as well as enteric infections. The dental dam or the plastic wrap[citation needed] are effective protection means whenever anilingus is performed. Anal sex has a number of health risks. 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. Exposure to the human papillomavirus (HPV) may also lead to the development of anal warts and anal cancer. Using lubricants can help some, but doesnt completely prevent tearing. The tissue inside the anus is not as well protected as the skin outside theanus. 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. 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. 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.

Can you relate to any experience or incident after which you started seeing these faces? How long has it been since they started and how frequently does it happen? Are you suffering from or are on treatment for any other disease/disorder? Any addictions to smoking, alcohol, drugs etc? If these faces have been appearing recently, just ignore them for a while.
