risk for STD's?

[nickjr1980]

Hey doctors,
One week ago, I had an encounter with a girl that I barely know. There was no intercourse, but here is the breakdown:
- She watched me masturbate for about 20 mins
- We went to eat and came back where I went down on her for about 30 secs (I was really paranoid about STDs, etc).
- She licked the tip of my penis (only once).
- We deep kissed.
- I masturbated her with my left hand and at the same time, I masturbated myself with my right hand, I am not sure if any of her fluids got on my penis.
- After she came, she tried to sit on top of me, and maybe (can't really recall, but if it did, it was very quick) her vagina touched my penis, but I quickly put by hand over my penis to block her.
- I washed my self and hands with soap right after this.
- Yesterday, I vigorously masturbated and again today.
- I had a minor sore throat about two days after the female incident.

Today, after masturbating, I noticed what looks to be a light-colored spot which leads into a a light-colored line, right near the head of my penis.  I imagine this could be from my masturbating, but not sure.  It is not a sore, the skin is not broken.  I am a white guy and maybe what I am looking at is always there, but the surrounding skin is irritated.

Could this spot be the formation of an STD sore?
What are my risks for STD's from her?  I asked and she said she gets tested each year, but also says that she doesn't like to wear condoms.  But, I again, did not have intercourse with her.

One more thing, she had some back acne, is that a sign of STD;s?  I saw something on the Net about it.

Most oral infections with STDs are asymptomatic. When people get STD symptoms, they get symptoms at the site of infection. Thus if your perform oral sex on a partner you might get oral symptoms (but probably not) if you acquired an STD while if you acquire an STD through genital sex, any symptoms would be in the genital region.

thanks for the response, you definitely helped me in not worrying as much.  My only follow up, and this is more for a medical education stance for me, since you stated that the oral sex carried a risk of gonorrhea and chlamydia (albeit low), would the symptoms still be in the penis region? meaning, puss-like discharge, pain while urinating?  Or would it stay at the mouth region.

Also, would one week be enough time for these types of symptoms to show up?

Welcome to the Forum.  You need not worry. STDs are spread by penetrative sex, not masturbation, not deep kissing and not by her licking your penis.  Your only risk was from performing oral sex on her and that risk is low. For starters, most women do not have STDs. Second, even if she did, most exposures to infected partners do not result in transmission. Third, there are few STDs which can be acquired through oral sex.  Gonorrhea can be but is uncommon. Chlamydia is rarely acquired through oral sex and if it is, there is no indication that it is consequential to one's health.  Other STDs like syphilis or herpes are typically acquired through direct contact with lesions and if that had occurred you would have seen the lesion.  

Regarding the discoloration you describe, this does not sound like an STD.  There is much variation in the appearance of normal penises.  On the other hand, sometimes after an exposure that, in retrospect, one wishes they had not had, persons tend to examine themselves and be far more attuned to genital sensations than in periods when they are not concerned.  This in turn leads to noticing what turn out to be normal sensations that might have been not noticed or ignored at other times.  Perhaps this was a contributor to your situation.  

My recommendation is not to worry., If you wish to be examined an tested, do so however before you do, please commit to believing the assessment of the clinician who examines you (I anticipate they will tell you there are no signs of STD).

Hope this helps. EWH
