Is Sucking Penis Safe?

There are several sexually transmitted diseases that can be transmitted during a blowjob -- in other words, when your penis is sucked or you suck someone else's penis. These include chlamydia, gonorrhea, herpes, syphilis, genital warts (HPV) and hepatitis B.

Concerning HIV, the risk is much lower, but transmission of HIV does occasionally happen.

There are many sexually transmitted diseases that can be transmitted in the context of close physical contact, even if no body fluids are exchanged. While using a condom during oral sex would reduce this risk to some extent, it won't eliminate it.

Anal and vaginal sex are the sexual activities during which HIV is most frequently passed on. In contrast, the risk during oral sex is low, but not zero.

If you suck the penis of an HIV-infected man, taking ejaculate in your mouth, there is a possibility of HIV transmission. (Engaging in other forms of oral sex, including cunnilingus, is unlikely to pose an HIV risk.) If you have bleeding gums or oral ulcers, or if your partner has genital sores or another sexually transmitted disease, the risk increases.

If you are concerned about the risks during oral sex, you should ensure you have regular screening and testing for sexually transmitted diseases -- especially if you have had oral sex with several people since your last check-up. If there is a particular sexual encounter which you are worried about and which you think may have exposed you to HIV, the best way to resolve these fears is by taking an HIV test.

  • HIV from Oral Sex Confirmed!!!!!
    I read the post from earlier today from the man that wrote he got HIV from Oral Sex. Will you and the "experts" now retract your assurances that Oral Sex is a low to no risk exposure and take a more strident stance that Oral Sex is a significant risk.
  • Possible Fellatio HIV Transmission
    I received unprotected oral sex from a sex worker for 15 seconds. I did not perform any other kinds of sexual acts. I ejaculated in her mouth.
