BV or YI?

[marrgarita.livejournal.com]

hey all.

lately, i've been dealing with some really badass itching down there.
it's completely external & has not been combined with any strange odor or discharge.
me and my boyfriend had sex last night & it didn't hurt during, but it was pretty sore afterwards.

the itching isn't always persistent, kinda off and on.

since going to the doctor is out of the question for a couple of months, i was wondering if maybe i should try using boric acid (as it clears out most bacteria, whether yeast or BV)
i wanted to dilute it and "mini-douche" as it says in the vulvapedia.
but i'm still a little confused as to how to do it.

so:
should i try using boric acid? it won't cause any harm if i dont have BV or a YI, will it?
or could the itching be due to dry skin, maybe? because its only external

and what can i do about the itching!!??

thanks =)
