V help

Look this is TMI and RATED R SO YEAH

I need a whole tutorial on how to keep my v... fresh I guess. I’ve been to several doctors and they told me that my vagina is clean and normal. But I’m terrified to ask my man to go down on me bc one day he ate me out, but not for long, after his penis had been in me for so long, I started to get freaky and pull it out to such him but I tasted it and well I was not satisfied.... send help, or answers
