Hey guys... the same happened to me and after going to the gyn a bunch of times, extensive research, paps, getting tested for every std, a colposcopy, and being declared completely healthy, now I'm pretty sure that I found the answer to our problem. It's called "FORDYCE'S SPOTS". Check this site http://www.howtogetridofstuff.com/health/how-to-get-rid-of-fordyce-spots/
Basically, just like you guys described it, it looks like itch-less, painless taste buds on your outer labia and if you stretch the skin they may appear kind of white. At first I was really scared cause they can look like HPV warts but they are NOT. It sucks because they cause no problem other than looking ugly. Although they are almost imperceptible, if noticed, who's going to believe you when you tell them that it just looks like you have something but you don't. Good news is that there may be something's you can do about it. So, the website said that there as some treatments to get rid of it but it's good to wait few months to a year of a diet rich of folic acid, vitamins A,C, D,E and B-complex cause they may be gone on their own. It seems like there they discourage people from getting the treatments cause they say it may be ineffective or the side effects may out-weigh the benefits, so be careful. Anyway, check the site for more info.
I really hope this was of help to all of you cause when I first noticed them I was freaking out and couldn't find a satisfactory answer, not even from my doctor till I discovered this. Now I feel much more relieved.
Good luck with your Va-jay-jays!
