STD's & Oral Sex?

Okay, say you were in a relationship with someone for about 1 1/2 years and all you engaged in was sex play and he performed cunnilgus on you. You did not perform fellatio on him. This was 2 1/2 years ago.
How likely would it be to have an STD? I have looked on medical sites and they state that:
1) Most teens with STD's is due to fellatio.
2) Cunnilgus is safer but not 100% safe.
3) From above actions, you would get Herpes, Shypllis and HPV. (The Herpes and Sphyllis would show definite symptoms in 2 1/2 years).
I have had an HIV test and it came up negative and the health care provider didn't seem to think I needed anymore testing. Do you think I should be concerned or worried? The man never had any gential scarring or sores of the like - we spoke about our sexual history (like I have none) and he informed me he was regulary tested. I knew the girl he dated beforehand, we became friends and she never voiced anything and neither has his new girl.
Serious Answers Please!

I have looked on Webmd with those doctors and also other medical sites, like charts with what is more at risk - it states receiving/performing cunnilgus known risks are: Herpes and possibly HPV warts. However, when performing fellatio the rates are higher because the penis is hitting the back of the throat.... so am I just being paranoid?
And yes, I know - I should get tested - but I want to allievate my mind for the time being until I can get in.
And no one word answers with no information. Anyone can do that for points.

I am not really sure what your concern is, if he has been monogamous with you, (and you with him) for 18 months then there would have been signs of an STD before now. And yes women are more likely to show signs than men are. The micro-organisms that cause STD's (bacteria, viruses, spirochetes) are transferred in body fluids, so yes saliva can carry these. The biggest danger you have if oral sex is the only activity that you have engaged in is Papillomavirus which has been shown as the cause of cervical cancer. Had you been engaged in fellatio there are many cases reported of syphilis and gonorrhea of the throat reported, both transferred in the male ejaculate. Human saliva can carry HIV but transfer by this method is rare as you would have to have open sores in your oral area.
To relieve your anxiety I would suggest you both get tested and then remain faithful to each other

I think you are worrying far too much. STD's are nasty and best avoided, but you are doing all the right things (including testing) and if anyone has you as a partner they are lucky because you care so much.

So stop stressing and just think about how you will avoid ending up in this position ever again.

Well done , you should be proud of yourself, not scared.

i think your over reacting a little if both of u don't have anything and your both faithfull to eachother then u shouldn't have anything to worry about. i don't want to scare u but some people never show signs or have symptoms of herpes, the only way to tell is blood tests or std tests.
