That could be a reason especially if you have contracted some infection to your part. Do get yourself examined by a gynec to see if there is any infection in your vagina. Smell is usually due to infection.
No i haven't been to a doctor or anything... The smell isn't badd, just different. And i can't smell it through my clothes or anything, it's when i put my finger in there, i've noticed it smells a bit funky... I dont have any other signs of infection either..... =S
