How Is STD Transmitted?

Hello, I would like to know if I had any risk of a std like syphilis, as I was for first time in my life in a massage parlour four days ago. I got a full body massage with oil, and at the end she gave me a handhob with her nude hands, no condom or gloves were used only oil massage, she was all time dressed and there was not sexual contac with her genitals . The room was dark and I could not see any wounds on her hands. after eyaculation she whased her hands. I am a little concerned cause I was reading on the net that there are possiblities of skin to skin transmission with syphilis, herpes or papiloma. I am circumcised. What types of risk I could get after that situation?. Thank you
