Okay so I'm sixteen years old and I NEVER had sex before. But one day my boyfriend fingered me and stuff like that. And every since then I noticed this yellow sticky color in my underwear.when ever I take I shower it burns and itches really bad. I have to shower at least 3 times a day to get ridd of the smell and the wet mushy feeling. But I don't want anyone to know about it. What does this mean?? PLEASE HELP ME!!
