Hello I am a 20 year old, and I have a problem with the color of my vagina, and the smell.

I do have itching but only sometimes. It usually hurts on the outside and inside when I have sex, and lately to the touch, it stings. My vagina smells strange, and fishy sometimes, other times it smells ok, but never the way it used to. The scariest part of whats happening, is that the inside of my vagina is not pink anymore, it is coated in a white film. I don't know what it is. sometimes I bleed after sex occasionally, but I always have, so it may have nothing to do with it. I am afraid that my new boyfriend I have been dating for nearly a year has given me something. before him I had a very pleasant smelling and pink looking vagina. When I deutsche it helps, but after I have sex with him, the smell comes back. It has steadily gotten worse other the past months and the pain is also getting worse I dont even want to have sex anymore. I also have a white dicharge which is strange. as it used to be clear.

Please help I think If i do not get help from this post I will go to the gynocologist, even if I do I still may go I just want to see if it may just be a bad yeast infection first.
