Vaginal Health :: Rough / Bumpy Area Above Vagina Hole

This is something I remember having as long as I've been paying attention to my vagina. But, I'm not sure if it's normal that just above the vaginal hole (inside my labia), instead of going in, my vulva (I think that's what it's called) goes out and there are tiny rough lump things.

I have ignored it until now because I assumed that it was normal. It isn't very noticeable or discolored or itchy - but if i rub it or touch it too much it is ever so slightly sore (but that could just be because the vagina is sensitive?).

Also, very occasionally I experience a very faint, not painful burning-type sensation when I pee but I always assume it is because I haven't had a shower in a while and it usually goes after I wash.

Oh, and I get a lot of discharge, too. I think this is normal because it isn't a weird color or anything but it comes out in a big lump sometimes if I haven't gone to the loo to wipe it off in a while. I wear black underwear and it appears white on top of that.

I really don't want to go to the doctor unless completely necessary, but could someone please let me know if I'm going to have to see a doctor or if it is normal? By the way, I'm a complete virgin and haven't ever had any kind of oral, penetration, or anything else, sex. But, I have masturbated.
