Thanks doc for answering this!
I am a gay. Days ago, I had a lot of French kisses with a guy. Then he gave me oral sex, about 10 minutes. Later, before i gave him oral sex, (which means i did not suck his penis), I found a chancre on the glans of his penis. He told me he did not even know there was a chancre. Then i stopped everything. This was no sexual intercourse at all. As you can expect, i was scared to death...........
Now, my question is:
1- what is the chance of getting syphilis?
2- how long should i wait to get tested?
Thanks again!
