Hi , I had protected sex with an escort the other night and have read enough to know that HIV is low risk. However, what are the chances of getting some of the other STD's like syphilis etc. What area of skin would need to contacted with syphilis in order to be transmitted. If it is just skin to skin contact could you get it by touching an infected area with your bare hand? Thanks for your input. Any input would help. (I have learned my lesson and will not be doing this again as I am so worried).
