I (27M) had unprotected sex with a (25F) stranger after meeting up at one of the websites. She wanted me to cum in her and shared her results (also specifying she has IUD and is infertile) that she does not have std’s so I did the deed.

Now I am very scared as this was my first instance of not using a condom. I am sexually active but always used one.

I also got to know that she has had other partners since she was last checked for std’s.

Can I take a pill or something to lower my chances of std/sti’s ? Its been 24 hours. Internet says some kind of prep but I am very scared to take a pill for a month as I suffer from other illnesses too (sleep apnea, heavy weight). Is there a 1-time sort of pill that will affect my body less??

I do not have a PCP. I have insurance but do not qualify for benefits as i make low wage but at a big company.
