I gave oral sex to a woman and i am worried about contracting herpes, hpv, warts or somthin. i heard to get something oral is rare is this true?

Mostly true: Oral sex can be considered safe sex. It's not completely free of STD risk, but low risk for all STDs and zero for some. Altogether a lot safer than unprotected vaginal or anal sex. Risk is especially low for cunnilingus (oral-vaginal). Oral warts and herpes in particular are rare from oral sex. No need for testing if no symptoms (sores of lips or tongue, sore throat) in next 1-2 weeks.
