I agree with you totally on that,girl. I had a guy i was going with for 10 years and every time we had sex i would come down with BV. I didnt know much about it then and my GYN told me that our sperm didnt mix . I even went as far as sending his ass to a specialist because any other man i was with i never got it . So your partner doesnt have to be messing around , now when i see him we use condoms
