really impossible for us to answer that question. as was already stated, it's very low risk and not worth much worry over.
It's been 7 days since I received oral sex..and I have not had any symptoms of a bacterial STD do you think I'm in the clear ?
normally 2-5 days for bacterial and maybe 2-3 months for herpes or HPV. But those are very low risk.
Ok well if I do have symptoms how long will it take before they show up?
the risk of a std from oral sex is rather low. we generally don't recommend testing for std's from it unless you have symptoms.
it's always in your best interest to only give and receive protected oral sex. keeps you from having to pay for std testing as well as keeps you from having to worry.
sexuality is completely healthy :)
