std probability

[stupidrisk]

Hi Doctor,

I'm a 26 year old straight male and on Friday night (four nights ago) I met a woman at a bar whom I eventually made out with and received fellatio from for maybe a couple mins. I told her I wouldn't ejaculate because I was drunk so we stopped.

The next day I noticed that my lower lip seemed to have a red mark on it, presumably from her biting my lip while kissing me earlier in that night.

On Monday (about 3 days after the incident) I noticed a large bump on my upper lip. It didn't at all look like HSV (from pictures) but I was worried it was beginning to form into HSV 2 so I called a dr and applied blistex. The bump completely disappeared when I got to the dr that afternoon. I asked him about my chances of getting HSV 1 or 2 genitally as this was my main concern at the time. He told me that since I've had cold sores before (HSV 1) I'm unlikely to get it genitally and that HSV 2 is rarely carried orally so my chances of contracting it via fellatio is very slim. Does this sound right?

Do I have anything to worry about with HIV? I didn't notice any sores around the woman's mouth.

What are the chances that I contracted another STD via fellatio?

Lastly, I'd like to point out that today (day four since the incident), I've noticed that I may have a low grade fever and I also felt like I was starting to get a sore throat (common symptoms for STDs) but I haven't noticed anything irregular on my genitals or while urinating as of yet. The previous day I was checked by my doctor and I apparently didn't have any issues with my lymph nodes around my chin and neck, nor did I have any signs of a sore throat. I suspect a lot of this may be due to anxiety, but I'm not sure.

From what I've read I believe my chances of contracting HIV or HSV (1 & 2) are very low. However, I'm not quite sure as to what my chances are of contracting another, albeit curable, STD is. Would you please give me a professional opinion on this matter?

Thanks!

Thank you doctor!

I didn't have any signs of a fever or sore throat when I woke up this morning. I think it may simply had been due to the anxiety.

This forum is a great resource.. Thanks once again for your help!

Welcome to our Forum. The interaction you describe is virtually no risk for herpes or HIV.  That you have had cold sores means that you are not at risk for getting HSV-1 again at any location so this is not a concern.  As for HSV-2, again the risk is incredible low, so low that it is difficult to provide any estimate of the risk.  

The lesions you describe are not suggestive of HSV either. The description you provide is not suggestive and a new HSV lesion would not be expected to go away so quickly.

As far as HIV is concerned, don't worry.  The quoted figure for HIV risk, if one has oral sex with an infected partner is less than 1 in 10,000 and, in my estimation that is too high. Some experts state there is no risk at all from oral sex.  Neither of us on this site have ever seen or reading the medical literature of a convincing instance in which HIV was passed by oral sex.

Following receipt of oral sex, the only STDs you are really at risk for are gonorrhea or non-gonococcal urethritis (NGU- this is not chlamydia.  Chlamydia is almost never transmitted or acquired through oral sex).  Bottom line however, I suspect you have very, very little to worry about.  If you feel you need to be tested, the only tests I would recommend are a Gram stain for the diagnosis or NGU and a test for gonorrhea.  At this time there is no need for therapy of any sort.

I hope this comment is helpful.  EWH
