Hello, I'm twenty one, but I was raised by my father and have never really had the confidence to ask anyone for help or advice. My mother and I don't have a good relationship and it'd be too embarrassing to talk to her, anyway.
So I have a few different questions and I intend to bother anyone who will read this with them. XD
Vaginal aesthetics -
I have olive/golden toned skin, but I don't get much sun. I think my vagina has a little too much melanin in it. The lips, overall, look a little dark, but the edges are almost black (I think) and they have sort of a... ridged look to them. The right side is a little longer than the left, just long enough to 'peek', but it doesn't really bother me. The skin on the edges is fairly thin, but again, doesn't really cause me an issue. Mostly it concerns me that it may be abnormal or something. It doesn't help that my pubic hair is thick and dark. @_@; All the hair on my body seems mismatched - pubic hair and eyebrows are solid black and coarse, hair on arms is light brown and fine, legs is thick and black, hair is brown. XD
Tension/light burn/gas? -
Sometimes, just before I finish masturbating or while I'm trying to, my... I'm not sure what the medical term is. XD Entrance? I can't remember, for the life of me.

When it starts to get really tight, I feel this weird... it's a burning, I guess, and it's more annoying than painful. I'm a virgin (by choice! XD) but my hymen is slightly pierced, and if I slip even the tip of my finger inside, it seems to ease it pretty quickly, so could it just be liquid/gas getting trapped behind the hymen? A pressure issue? Maybe even related to dryness? I can be a little dry sometimes and a little wet other times, so I'm not quite sure.
Someone told me the wetness/dryness issue was likely anxiety, since I have a hard time with that. @_@; Anyway. Sometimes, too, it just feels like there's gas trapped in my vagina. Is that normal? It comes out and everything and I worry that it's gross and weird. Is it?
This is everything I can think of right now... all I can hope is that there isn't anything too strange.
Any assistance besides just 'see a doctor' is appreciated. I haven't seen a gynecologist yet due to being overly shy (and, as noted, anxious) and lacking in funds, but I will if I absolutely have to.
