Has anyone else had this problem??please help

I have been with my now husband for 2 years and I was not a virgin before we got together well the issue is I am CONSTANTLY getting infections either yeast infections or bv or one time I got some cervix infection and another weird one I have never heard of before none of them stds and we are both faithful..I don't understand it's like I'm having a some adverse reaction to him and it makes me want to cry...I have never had this problem before..I always pee after sex I stopped taking baths(only showers now) I don't use any soap down there just water and I even stopped using tampons why is this happening? And also when he cums in me its like this weird bad smell that last for a few days what is this??? I don't know what to do it keeps happening and we moved and now I have to drive an hour to see an obgyn and I don't want to be doing that every other week we are ttc and I feel like I don't even want to be touched half the time bc I know what will happen...we have a lot of sex or we used too now his feelings are hurt bc I just don't feel like it anymore bc it's embarrassing he says he doesn't care and I shouldn't feel that way but he doesn't understand how it's making me feel I feel like my vagina is broken lol omg please tell me someone else has went thru this
