Philo you are so stuck in this obession with sex acts, that it borders on concern.
By the way anal sex is a common sex act in hetrosexual relationships and hetrosexual marriages, as is oral sex. Therefore what consenting adults do in their own home, is none of your business.

Philo,

If a man engages in a homosexual act, it is because he is homosexual or bisexual. Heterosexual men are not sexually attracted to other men, and consequently do not have sex with them (consensually, at any rate). I advise that you invest in a new dictionary, 'coz the one you're working out of is at odds with the common usage of English.

I find it interesting that only male-to-male anal sex which is abhorrent. Does that mean that if homosexuals only engage in oral sex, they're not really gay?

Kipp,
That is why we have a high degree of cervical cancers, from bacteria from the bowel entering the sterile cervix.

It is certainly a concern as taxpayers we have to foot the bill; as they do for bowel tears.

Philo,

Nearly all cases of cervical cancer are caused by HPV, a very common STD affecting ~80% of sexually active people. HPV stands for human papillomavirus - a viral infection, rather than a bacterial one, and one which spreads readily through all forms of sexual activity. It does not, however, infect the bowel: HPV only infects the basal cells of stratified epithelium, and the bowel is lined with columnar epithelium. Whilst you're shopping for your new dictionary, I suggest you pick up a biology text book too.

The Acolyte Rizla,
The bowel is a point of excretion of all foreign matter to a healthy body including virus.

Anyway the "how" is just one factor here. All of those should be taken into account I have written about.
