Yes, a report issued in September 2005 by the National Center for Health Statistics was the basis of an article in the September 26, 2005 issue of TIME magazine. The report comes from the results of a computer-administered survey of over 12,000 Americans between the ages of 15 and 44, and states that over half the teenagers questioned have had oral sex. This was the first comprehensive study of its kind to examine the matter.***

MEDICAL MATTERS
After knowing the medical terms let me reply to your first question.
Reply: "MEDICALLY ORAL SEX IS SAFE, JUST AS ANY OTHER SEX IS, BETWEEN CONSENTING PARTNERS."

What are the pros:
no risk of pregnancy.
part of foreplay or after play.
richer experience of sexual joy.
In women who are otherwise an orgasmic, cunnilingus could be part of treatment, if both the partners are willing.
You say: It is unnatural? Mouth was not meant for using on the genitals.
Reply: Penis inserted in vagina is natural. Mouth to mouth kissing should also be considered unnatural.
You say: In kissing both partners enjoy. It is not unhygienic.
Reply: All people do not necessarily like mouth to mouth kissing, just as all people to not have to like hamburgers, samosas, or dosas. In cinema kissing had to be extensively used because nothing further was permissible.

Hygiene: There are more bacteria in your mouth than there are people in this world.

Hygiene: Compare to Mouth to Mouth Kissing, Oral Genital Kissing is more hygienic if you consider the number of bacteria in mouth.
It is agreed that oral sex, just as conventional penovaginal sex, is to be done between mutually consenting partners who maintain general hygiene, specially, cleansing mouth, brushing your teeth, bathing. No sweat odors, no bad tastes.

TIP: TAKE A BATH BEFORE ORAL GENITAL SEX

In both fellatio and cunnilingus it is important to note that the person who is orally stimulating does not get direct pleasure, but indirect pleasure of satisfying the partner.
Sexually transmitted infections (including HIV)
The risk of contracting chlamydia and HPV through oral sex is rare, although possible, if the fluids come in contact with open skin or mucosa. The risk is definitely far lower than that associated with vaginal or anal sex.

Cons

HPV and oral cancer link***
A
In 2005, a research study at the College of Malmö in Sweden suggested that performing unprotected oral sex on a person infected with HPV might increase the risk of oral cancer . The study found that 36 percent of the cancer patients had HPV compared to only 1 percent of the healthy control group.
B
Another recent study suggests a correlation between oral sex and head and neck cancer. It is believed that this is due to the transmission of human papillomavirus (HPV), a virus that has been implicated in the majority of cervical cancers, and which has been detected in throat cancer tissue in numerous studies.
C
The New England Journal of Medicine study concluded that people who had one to five oral sex partners in their lifetime had approximately a doubled risk of throat cancer compared with those who never engaged in this activity and those with more than five oral-sex partners had a 250% increased risk.

If you ask about methods of prevention for the above when a partner's status of STI is unknown is to use condoms (flavored condoms are available)or use of dental dams in fellatio.

Prevalence, sociocultural aspects will be dealt in another post.
