STD in the mouth is caused from oral sex with an infected person.
No; period.
Oral sex cannot lead to pregnancy, but oral sex can transmit STDs.
It's not harmful assuming none of the people have STDs.
by this you mean putting the males genitles on a females/males face, no. there must be blood to blood contact.
Come on, the same way heterosexuals do. By having sex with a person that has a STD.
Flavored condoms for oral are more for protecting against the body fluid contact for transferring STDs. If the guy is clean then there shouldn't be a need for a condom.
Trichomoniasis is cured with oral medicine, not injections. Gonorrhea and syphilis are STDs cured with injections.
Oral sex - or fellatio.
Yes oral sex is the stimulation of the sexual organs with the mouth, this can be done to and by both males and females.
- Very satisfying finish for some people. It can boost the amount of a partner's orgasm/pleasure. Perform only if you trust your partner (no gonorrhea, trichomonas, chlamydia, HIV, herpes, or any STDs). - There is less chances of getting infected (STDs) by oral sex comparing to intercourse or anal sex. Even if I said "less chances," it does not mean the oral sex have some "preventive measures" against STDs or HIV. - And of course, you can't get pregnant.
Both through oral sex and anal sex - especially unprotected sex - you can transmit diseases (STDs).
More males than females smoke cigarettes, chew tobacco, smoke pipes, and use snuff. All of those things can cause oral cancer, and some can also cause lung cancer.
