What is wrong with my vagina?

Ok, so since about mid summer 2010, my vagina has smelled way different then it use to. I'm having a lot of discharge all the time, sorry to say this, but if i wash my hands and put a finger in it an pull it out, its all wet with whitish discharge that is sticky and has itty bitty chunks in it. It is worse after I masturbate, have sex, or sleep or go more than a few hours without washing it. The smell is like sweaty musty with a hint of fishyness:/ and really noticable after sex. My vagina didn't do this until me and my now ex boyfriend started having A LOT of sex without condoms. His penis always stunk no matter how hard he scrubbed it or what he washed it with. What could this be? Please help me! ( And no, I know for a fact it is not a yeast infection, I sometimes have a little itch though, but it isn't a yeast infection.)
