Risk of std?

I’ve had my first sex experience a month ago and second one a week ago. We did not use condom and I noticed this red spots on my vaginal opening from 3 days ago. Does someone know what it is and how to take care of it?

Any symptoms? Itchiness, soreness, pain when peeing?

Just discomfort and little bit of itching

Its likely an STD, because STDs and pregnancy are the most likely results of unprotected sex.
