hi, i had sex with a sex worker today and performed oral sex on her twice. a few minutes before having sex, i ate a sandwich- the bread was rather hard to chew and i felt it hurt my gums. after the sex i realized a rather large section of my gums and roof of my mouth are sore and red. i realize i am at risk, but i am wondering how much of a risk are we talking about? i should also mention that i was actually trying not to get any vaginal fluid in my mouth and spitted out regularly. tnx
