Is it safe to have oral sex?

Yes but only if . . : Protected. It's still very possible to catch or transmit sexually transmitted disease/infection via oral sex w/o protection. Presumably you'll be safe from pregnancy. Of course, if you're in a mutually monogamous relationship, then "safety" really isn't an issue. Otherwise, plan to use some form of protection, eg condom or dental dam (http://en.Wikipedia.Org/wiki/dental_dam), altho not very sexy.

Yes and no: It's a tricky question. If you are with one trusted partner and it causes no discomfort to you and her and it is consensual on both sides and brings pleasure to both of you, then - yes. If the above are compromised, then it may not be unsafe for you or your partner and may not be nearly as pleasant.

Yes, but...: If your partner has HPV, Herpes, and several other STDs, you can acquire these orally! The number one cause for throat cancer is HPV. Know your partner well!

Oral sex: Oral sex can still lead to passage of sexually transmitted diseases, hence it is advisable to also practice "safe oral sex" as well. Know your partner.

STD risk: While there is not a pregnancy risk with oral sex, the spectrum of sexually transmitted infections is up for grabs. Condoms or dams can provide barrier protection from these while enjoying the experience.

A women should use..: A condom on a man, particularly a new partner. HPV, Herpes, and other STDs can be aquired. Use caution with a new sexual partner!
