I am 23 years old and I am extremely self conscious about vaginal odor. I don't like my boyfriend to perform oral sex because I am so worried that I smell bad. I scrub and scrub my genitals in the shower but an hour later the smell is back. When I asked my OB/GYN about it he said that he would check me for STD's but never explained anything to me. I haven't had an STD ever and I have had this since I was 13, what is it? How do I know if its normal? Please help!
