Sexually transmitted diseases, commonly called stds, are diseases that are spread by having sex with someone who has an std. You can get a sexually transmitted disease from sexual activity that involves the mouth, anus, vagina, or penis.

Let's just say I don't know of any that you can't get in your mouth with oral sex. I know that you can get chlamydia, hpv, herpes, warts, even bacterial and yeast infections all in your mouth. So, yeah, basically at least most of them you can get from oral as well as through intercourse.
