Thank you for taking time to read my question.
This incident happened around two years ago during my first year at college.It was my first, and only sexual experience. I engaged with 'frottage' or genital rubbing with a circumcised man, who told me he did not have any STDs. I'd asked him that already. Now I know pre-ejaculatory fluid contains HIV. I read that this is only dangerous if there was penetration. But i'm unsure of what the word 'peentration' means, since i know he didn't enter me. but if he did even slightly, would I have felt it? I'm sorry for these questions, i guess it's due to my lack of experience.
My fear is that he does have an STD,but is just not aware of it. I usually have yeast infection-like symptoms, and hence me worrying if i am HIV+. I also had a bad case of tonsilitis, which i had never had before.
Many thanks to everyone who takes the time and effort to reply
