Vagina Problems!!

its so hard for me to be attracted to my bf or wanna have sex with him because his semen makes my vagina smell like roadkill!! and its only him ive been with other men unprotected and it was never like this. it makes me hate when he touches me!! nothing helps i take the probiotic fem dophilus and everything. this is ruining my self esteem !! i dont know how much longer i can deal with him. and i know you girls are gonna say just use a condom but he refuses if we have to use condoms he doesnt wanna have sex at all!!
