Suggest Medication For Itchiness In Vagina

for years I have had a problem with itchy virginal I 'm embarrassed to tell the doctor so I deal with it . I notice when I get nervous that when it happen the most .my husband have gotten use to me scratching and he tells me that the reason I'm inching is because my nail have germs. I can take a bath 2 or 3 times and I still can itch afterward. well around my virginal my thighs are can of thick and sometimes it can get a little hot down there so I will go and wash and use a itching cream are something. but when I focus on something else I forget about it and its gone until the next time I get nervous. what could this be ?
