I know, weird question. today someone told me that if a girl has had sex with a lot of guys, her vagina will have an unpleasant smell. He said it had something to do with the "scents" of all the guys she has had sex with; I'm not sure exactly how he explained it. This kinda has me worried because lately my girlfriend's vagina has been having an unpleasant smell. When we first met she was a virgin and it didn't smell at all, but for a while now it has not been smelling very good at all, and after hearing what my friend said i thought it may be a possibility that she may be having sex with other guys. This idea sounds a little far fetched to me, but i am not very sexually experienced so that's why i am asking about it. Is this true at all, or did the person that told me this not know what he was talking about?
