Basically, I have had this annoying itchy feeling in my vagina like inside of the flaps sort of area.. like the moist part. It randomnly starts to annoy me and then i itch it but go too far and then it starts to hurt, sometimes even bleed.

Ive only had sex without a condom with one person and i do know that it could only take that one person to make this happen but it was like this briefly before i had sex with him but it went away before so i thought i might have been allergic to something like certain washing detergents...

a few months later a sort of spot was like near the bottom of my vagina,(on the left flap, erghh) but it went away a few weeks later.. this is when i started to notice that something may be wrong.. nothing like that has come back or happened again.. and its been a good while now and if it was going to come back it would of.
But I do still have this annoying itchiness. Its more or less ok when i leave it, but when i go toilet or have a shower after itching it. The only thing that i found soothes this is having a shower with hot water.. I may be over exxagerating because sometimes i get iritated and may wipe myself with tissue too hard.
I read something where it says that one of the reasons is that i could be either washing my vagina too much or not washing it enough but i think it would be more along the lines of washing it too much..
i also read something saying that you should use soap... but i thought that was wrong to do,which means i havent done that... i havent gone to the Dr because i am really worried and i have NEVER spoken to anyone about this before...

So i feel like i need someones advice before I go..

Please help me asap!!
