Protected oral sex risks

Doctor,

I'd first like to apologize for these paranoid questions.  I'm struggling with some sex addiction issues.  So if I sound obsessive I'm sorry.  I visited a female escort in Vancouver 12 days ago and recieved protected oral with a condom.  She did suck on my scrotum breifly a couple of times.  I was naked on top of her bed for about 15 minutes.  I have a couple of questions regarding my STD risks.

1.  How much of a risk am I of catching syphilis or herpes?  I did shave my pupic hair about 2 days before this I was with her and now have a small single blister which looks like an infected hair at the base of my penis.  Could this be syphilis or herpes?  

2.  How much am I at risk from her sucking on my scrotum?

3.  If I was efected with syphilis or herpes does that put me at risk for HIV?

4.  What are the chances of me cathing scabies from her or laying on top of her bed for 15 - 20 min?

5.  Should I get tested for any STD's if so how long should I wait to do this and what test should I have?

I didn't notice any sores or blister around her mouth,  but I really didn't look and check.

Thanks for your help

Welcome to the Forum.  the exposure you describe is associated with little risk for STD of any sort. Condom protected sex is safe sex.  Kissing and "sucking" does not carry risk.  In answer to your specific questions:

1.  Shaving 2 days before your exposure does not change your risk.  Syphilis and herpes are most likely to occur if you were in contact with a lesion,.  If you did not see a lesion you have little risk. Furthermore, syphilis is very rare and therefore not a concern.  As for HSV, if you do not develop lesions in the 4-10 days following your exposure, you really do not need to worry about herpes either.
2.  Zero
3.  Persons with syphilis or herpes are at about a 3-fold increased risk of getting HIV if exposed.  You are not likely to have either infection and are unlikely to have been exposed..
4.  Miniscule
5.  There is nothing in the history you provide to suggest that you need STD testing.  If you wish to be screened for infections you might have had before the exposure you describe, you would want to be tested for gonorrhea, chlamydia, NGU, and HIV.

Hope this helps. Try not to worry. You really are not at risk from this exposure.  EWH
