Oral sex more likely to lead to throat cancer than smoking: Study

What about anal?
 
Ya but bacteria are filtered away internally. They come out from the back not the front.

Yup the bacteria that is in shit comes from the body's intestines especially the large intestine.

Humans like all large organisms have a huge population of good and bad bacteria inside them.

lianbeng adds 2 cents, "certain bacteria belong to certain area in the body, eg anus, and they are very safe there but once they migrate to elsewhere, eg mouth, war will start.":D
 
Don't poke the mouth. Poke the ear instead.

I respect you. You can fuck elephants !:cool:

Come to Chiangmai. The elephant shows have been pretty boring, but I think your stunts will be a crowd puller.

Human papillomavirus (HPV) is a member of the papillomavirus family of viruses that is capable of infecting humans. Like all papillomaviruses, HPVs establish productive infections only in keratinocytes of the skin or mucous membranes. While the majority of the nearly 200 known types of HPV cause no symptoms in most people, some types can cause warts (verrucae), while others can – in a minority of cases – lead to cancers of the cervix, vulva, vagina, and anus in women or cancers of the anus and penis[1] in men. It can also cause cancers of the head and neck (tongue, tonsils and throat).[1]
More than 30 to 40 types of HPV are typically transmitted through sexual contact and infect the anogenital region. Some sexually transmitted HPV types may cause genital warts. Persistent infection with "high-risk" HPV types — different from the ones that cause skin warts — may progress to precancerous lesions and invasive cancer.[2] HPV infection is a cause of nearly all cases of cervical cancer.[3] However, most infections with these types do not cause disease.
Most HPV infections in young females are temporary and have little long-term significance. Seventy percent of infections are gone in 1 year and ninety percent in 2 years.[4] However, when the infection persists — in 5% to 10% of infected women — there is high risk of developing precancerous lesions of the cervix, which can progress to invasive cervical cancer. This process usually takes 15–20 years, providing many opportunities for detection and treatment of the pre-cancerous lesion. Progression to invasive cancer can be almost always prevented when standard prevention strategies are applied, but the lesions still cause considerable burden necessitating preventive surgeries, which do in many cases involve loss of fertility.
In more developed countries, cervical screening using a Papanicolaou (Pap) test or liquid-based cytology is used to detect abnormal cells that may develop into cancer. If abnormal cells are found, women are invited to have a colposcopy. During a colposcopic inspection, biopsies can be taken and abnormal areas can be removed with a simple procedure, typically with a cauterizing loop or, more commonly in the developing world — by freezing (cryotherapy). Treating abnormal cells in this way can prevent them from developing into cervical cancer.
Pap smears have reduced the incidence and fatalities of cervical cancer in the developed world, but even so there were 11,000 cases and 3,900 deaths in the U.S. in 2008. Cervical cancer has substantial mortality in resource-poor areas; worldwide, there are an estimated 490,000 cases and 270,000 deaths.[5][6]
HPV vaccines (Cervarix and Gardasil), which prevent infection with the HPV types (16 and 18) that cause 70% of cervical cancer, may lead to further decreases.
