Oral sex question

[Leo_oo]

Hi  everyone. Im a 20 year old male. A month days ago a prostitute made a ******* for me, in a condom. But when I came home (15 min later) I found a little scratch on my penis, clother to its head ( on the outer side of penis). The problem is that I dont know, if it was made by prostitute's nails before the ** or by her teeth in the process. I dont know if she had bleeding gums or something like that, but I didnt notice any blood on the condom. When it was finished, the condom seemed okay, I mean the sperm wasnt going from it. But I'm not 100% sure, as it was dark there, so maybe there was just a micro hole in the condom. As I got home, I've put some liquid soap on the cut, and there was mild pain for a couple of seconds but then it was OK. Now, the cut is almost invisible.
So could I get HBv, syphilis or other illnesses from this contact? Im worried now, please give me an answer.
Ps: sorry for my English
Pps: no symptoms yet

No need to test as you had the condom

Thanks. But Ive read that syphilis or herpes can show no symptoms. So maybe it is worth testing? Or there was no risk in my situation? Most worried about the cut. And she was African, it it changes anything

The condom reduces it to zero

And does the fact that I was using condom reduce the risks?
Also can I get HBV from this exposure? If we suppose, that the cut was made by her tooth, and a little of her saliva entered the cut?

Oral sex, low risk for gonorhea, syphilis, hsv1 get tested if you feel symptoms. Otherwise no need to test.

Anyone know?

I should add that the process wasnt long, about  3-4 minutes, and after it I masturbated until it was done. I've read that if there was a crack in the condom, it would break when I started masturbating in it after the oral sex, is it true? Please, help
