Herpes or possible yeast infection

After having sex with my partner, I noticed a lump located in between my labia majora and labia minora about a day later.  It is located on the inside of my labia majora.  The lump was hard and didnt appear to have anything inside of it. I played with it which resulted in it growing a bit bigger.  After about a week, it disappeared after leaving it alone/some neosporine/vaseline.  It didn't burn/cause any discomfort.   It never scabbed.  I also performed oral on him, but I did not get any lesions on mouth.  If it is herpes could it be possible to get a lesion on my vagina and not on my mouth. Three weeks later bump appeared again in the same place.  The day before I had vaginal and anal itching (inside the vagina itching) It did not itch where the bump appeared. I thought it could be an ingrown hair because it had two holes in it.   I picked at it with tweezers.  (bump is on the left inside of the labia majora (by hair and some type of glands). After picking at it for some time the bump turned more of a blister.  It is slightly raised and filled with clear liquid.  I tried to pop it, a tiny bit of clear liquid came out, but it would not pop.  It does not hurt when I touch it, burn when I urinate, burn when I get urine on the lesion.  My lesion doesn't resemble any herpes pics I have come across.  I do not have the typical symptoms of genital herpes, except the lump turned blister.  I have two friends that have genital herpes and they said I would now it because it is very painful.  I do have the vaginal itching (inside) and my vaginal secretions are milky white (but not cottage cheese).   I have read on other forums that a yeast infection can cause a lesion in the area that I have mine because it is dark and moist.  My labia minora covers the lesion.  My main symptoms: lesion, anal itching, inside vaginal itching and some milky discharge that is odorless.  Could this possibly herpes?  How long does it take for a herpes blister to burst and turn into an open sore.

What you describe is in no way suggestive of genital herpes.  The location and characteristics of the bump you describe and associated symptoms are most compatible with a vulvar cyst.  These are benign, non-infectious processes which can come and go and tend to cause no particular discomfort.  Alternatively, it could indeed be folliculitis (a hair bump).  Neither a cyst nor folliculitis is an STD.  In addition, either way, for you to pick at it is absolutely the wrong thing to do.  This could lead to infection and much discomfort.  You have a reason to go to get checked out (see below). At that time, ask the health care professional to take a look but, until then, please do not pick.

Your symptoms of milky white vaginal discharge and vaginal itching are not normal  these could be symptoms of any number of infectious processes, some of which are STDs (trichomonas, chlamydia, gonorrhea) and some of which are not (bacterial vaginosis, yeast).  the only proper way to get this sorted out is to go get checked out by a health care professional.  

Hope this helps.  Don't worry about herpes but your problems do warrant a visit to a health care provider.  EWH
