Recently, I started having sex with a new guy, and we are in an exclusive sexual relationship now for about 5 months. We had sex Thursday. Friday I had a lot of watery discharge no pain, itch, or smell. Then Friday night I noticed a yellow/green chunky discharge, like chicken fat, very small amount still no smell or itch. Saturday I started having severe pain when urinating and when anything touches my vaginal opening. Very painful. I took a mirror to look at the area and I have redness on the inner lips and opening that looks like the skin is missing. I have noticed blood. I am close to my monthly so I tried to insert a tampon. It hurt so I had to take it out. Do I have some type of infection or did I just hurt myself during sex? Still no smell and the yellow/green discharge I don t see.
