About something like pearly penile

[xdq]

Hi, doc,
Recently, I went to Amsterdam and I had sex with a prostitute in the red light district which now I think that is the most stupid thing to do ever. And I used a condom the whole process both oral and normal vagina sex, the process was very short like 5 minus. After finished sex, I washed the penis immediately. Four days later, there are one row of small spots grow in my penis which looks like pearly penile but not that severe, and eight days later, the small spots become several rows. The spots are not hurt at all and they are really small, only when I get erection then they are obvious.Now It is the 13 days after the sexual contact, and they seems like growing little bit but still not look like as severe as those pictures on the Internet. It looks like the half size of those spots of the picture from the following web (http://www.usc.edu/student-affairs/Health_Center/adolhealth/images/b4derm6_clip_image022.jpg) My questions are:
1: Are these spots harmful, are they STDs? If they are STDs and how it is possible that they are passed to me even I used a condom. Or they are just the pearly penile?
2: If they are pearly penile, are they caused by the dirty environment in the red light district?
2: Will I pass them to my wife during sex?
3: Should I just leave them until they grow as server as those picture in the google picture？ What should I do?
4: Can it be the symptoms of HIV? Plus I have no other symptoms.

Thanks

OK, and can you tell me how much chance for me to get HIV?

Since you are married, you must absolutely find out what you have.  Once you have unprotected sex with your wife, you have exposed her to a possibly contagious and cancer-causing problem.  Or it could be nothing.  Until you go to the health clinic, you won't know.  Just do it.
