Hello,
A few days ago I met a 38 year old married women whom I had oral sex with. She performed oral sex on myself and i briefly performed on her. I have no cuts or pain on my penis. I am in a long term committed relationship and the women is a married business executive (not that this mattesr, but I doubt she is very promiscous). Before meeting her I did have some small sores on my tongue (i think burns from pizza). What are the chance that I could have contracted an STD? Should I be tested for HIV?
