I wanted to know if I have been exposed to Syphilis or the situation I have recently been in exposed me to an infection.

I got a massage while me and the masseuse was topless. I noticed that the side of her breast had many brown spots that looked like pimples (not freckles). None of them looked like open sores. Her hands did not show any spots. After the massage, the attendant gave me a brief 5 second hug (Chest to chest) and peck on my chest. Within 30 minutes I had taken a shower and used body wash to clean myself. 

My questions are:

1. Can syphilis be transmitted by a 5 second hug (Skin to skin contact)? 

2. Did the peck on my chest expose me to syphilis or any other type of STI infection?

3. Should I get tested for Syphilis because of this situation?

4. In your opinion have I been exposed to a STI infection?

Thank you for you help
