Chance Of Getting STDs through protected oral sex

hi, it's been awhile since i've been here. Well i would just be straight to my question...

1. if i receive a full protected oral sex (and considering the woman tongue/mouth doesn't have any contact with unprotected part of my genital), would i ever have any risk of getting HSV1, HSV2, and syphilis? (i know the risk should be very small but I still want to know if it's very small2 one)

2. if i french kiss the woman, how big the chance of me contracting syphilis and other STDs?

3. I know the risk for getting HSV1 is there for french kiss (i havent had HSV1, already get blood tested 7 months after last time i kissed/had sex with someone), but is there any risk for getting HSV2 for french kiss alone?

sorry for such question but i hope you would answer it in details, even if the chance is very small i would still like to know?

Aside from syphilis and herpes, no STDs have ever been known to be transmitted by kising.  Of course other infections are very commonly transmitted by kissing, like cold viruses, strep throat, and other respiratory infections.

That will end this thread.  I would advise you to not worry so much about these things.

ok thanks so much for the details. just one more question if i may, how about the chance of transmitting other STDs for french kissing (beside syphilis and HSV), such as chlamydia and other bacterial infections? (assuming the girl has it in her mouth)

But since you're worried, I don't understand your reticence to ask your partner and perhaps go together for testing for STDs.  Mutual STD testing is pretty common in couples these days.  Properly proposed, most people would not take offense -- and you may find she is just as concerned about STDs from you as you apparently are from her.

Welcome back to the forum.

Responding first to the title you chose for your question:  Even without a condom, oral sex is low risk for STDs -- not entirely risk free, but much safer than unprotected genital or anal intercourse.  With a condom that remains intact, you can consider oral sex to be 100% safe, with no risk for transmission of any STD, either from the oral to genital partner or vice versa.

To your specific questions:

1) No risk at all for any STD.

2) In theory, syphilis can be transmitted by kissing.  In practice, it is exceedingly rare; in 40+ years in the STD business, I have never seen a case.  In addition, assuming you're in the US, you can safely count on female partners not having syphilis.  In the entire country, there are only a few thousand heterosexually transmitted syphilis cases each year -- compared, for example, with a couple milion chlamydial infections.

3) Oral HSV-1 is often transmitted by kissing; in adults, that's probably the most common mode of transmission.  French kissing is undoubtedly higher risk than more superficial, social kssing.  There is no way to estimate a numerical risk, but it's obviously very low in the absence of contact with an overt herpes outbreak, i.e. cold sore.  Although some cases probably are transmitted from asymptomatic infections, this appears to be rare.  Of course oral herpes acquired by kissing isn't considered an STD.  

Oral HSV-2 infection is rare, and therefore kissing rarely brings anyone into contact with the virus.  But if a partner had oral HSV-2, kissing could transmit it.

and as a note, the condition for above questions is if condom doesnt break at all and (again) there's no DIRECT skin to skin contact, just from the girl's mouth to condom (her mouth doesn't have any contact with unprotected part of the genital at all)

im sorry for such paranoid questions because it's been like 2 years since i really had sex (because i had genital warts) and i want to be sure to never ever get anything again as HSV is pretty common and to be honest i dont want to get it even though i trust my partner (but she could be asymptomatic you know and i would offend her if i ask her for blood test)
