What Are The Symptoms And Treatment For Vaginal Infection?

Hi I m Chloe and I m 18 years old. I lost my virginity 1 month ago and since me and my boyfriend had sex it s been few weeks now that we are having sex and just this week I experience this yellow stuff kinda like liquid and ere some white white stuff with it which is coming our from my hole and I need to rub it off as it s seems like a rubbing thing. Can you please let me know if it s an infection or is there a bacteria as it s my first time to face this problem.
