I had sex for the first time a few days ago with my boyfriend of over a year. We were protected and used a condom. Since that day I've been having discharge that started off a light brownish color and is now a light yellow color. It's not super thick and I don't think it really smells much different than normal and it doesn't hurt or itch down there. I would just like to know what's going on, and if it's normal. so if anyone might have an answer that'd be great.
