The reason I am asking this is that I have taken a look at my urine and have very small particals floating in my urine. I have no burning or discharge.

I had an encounter and had oral sex with someone.

My partner has also had a few days off with pains in her arms and legs also her fingers have swollen and she has pins and needles what are the chances she has contracted it we have sex but I always use a condom. We also have dry sex through clothing.

Also why is it that in America you do not test for chlymidia if only oral sex has occurred but in the UK they test. Is it because there could be a chance of it if only small. 

I am full of anxiety I have been for test and I am awaiting the results.

Could you explain the risks of all orally transmitted studs.

Thanks,

But oral sex is a different deal. In general, oral sex is safe sex. It isn't entirely free of STD risk, but the overall chance of infection is low for all STDs and virtually zero for some. All in all, far safer than unprotected vaginal or anal sex. There are differences for cunnilingus (oral-vaginal contact) and fellatio (oral-penile). The highest overall risk (but still very low) is for the oral partner in fellatio. The insertive (penile) partner -- which I believe if your main concern -- has three main risks: gonorrhea, herpes due to herpes simplex virus type 1 (HSV1, the cause of oral herpes), and nongonococcal urethritis (NGU). The last probably is the most common STD seen in this situation, and it could cause visible strands of mucus ("particles"?) in the urine. However, chlamydia has never been shown to cause NGU acquired by oral sex.

Chlamydia is extremely uncommon as a result of oral sex. Few people have it in the oral cavity, and the overall frequency of positive test results is too low to make routine testing a wise strategy, in the opinion of most experts. There are no "national" policies on this:  it may be true that more GUM clinics and other STD providers in the UK test for chlamydia in this situation than at most US STD clinics, but there are exceptions both ways. But since one would have to do perhaps a thousand tests to detect a single infection, at a total cost of perhaps $50,000 USD, you can understand why testing might not be routine in many settings.

Your partner's reported symptoms don't concern me at all. There are no STDs likely to cause them, and certainly none transmissible by oral sex.

You don't say whether you were closely examined for evidence of urethral discharge, or if a urethral swab specimen was used to examine for increased white blood cells. This is the main approach to diagnosing NGU -- which as noted, could cause "particles" in the urine. Also, despite my comments about chlamydia and oral sex above, you should still have a urethral or urine chlamydia test. Condoms sometimes fail -- that event, with a partner having sex with others, was higher risk than the oral sex event(s).

I hope these comments are helpful. Let me know if anything isn't clear.

I think what your are trying to say is that if the condom failed and I did have chlymidia it would mean my partner had been seeing someone else?

As I did not and would not have full sex with someone else

It's often difficult to know when and where any particular STD was acquired. That's especially the case for chlamydia, herpes, HPV, and other STDs that can persist for long periods, often with few or no symptoms. From all known so far, it is very unlikely you do have chlamydia, so the question probably is moot. However, this forum tries to not get involved in determining where and from whom particular infections were acquired. That's between you and your partner, and only if and when you are confirmed to have an STD. I'm sure you can find labs or clinics willing to test you -- there are no rigid national standards (and certainly no regulations or laws) in UK or anywhere else. With little difficulty, you can find a private STD clinic (e.g. London's Freedom Health clinic is excellent) or online testing resources. Or just discuss these things once again with the doctor or clinic you have already seen. My guess is that their policies are less rigid than you have said.
