I'll email you my answers in few minutes, but you'd get way more answers if you asked in Rock and Pop. ^_^
Edit: Answers! Woo!
1. How did you become a guitar player? When? Why?
I started playing in 2003. (I was 13) I loved writing lyrics and thought I should take up an instrument so I could write proper songs.
2. Were you influenced by any guitarists, or female guitarists, in particular? What are your musical tastes?
Until a few years ago the only female guitarists I was really aware of were Charlotte Hatherley from Ash and PJ Harvey.
I was influenced by Charlotte and the other guitar player in Ash, Tim Wheeler quite a bit but I was influenced a lot more by Carl Barat and Pete Doherty from The Libertines. I really like Nick McCarthy and Alex Kapranos from Franz Ferdinand as well.
My musical tastes are pretty varied. I can't really pin it down to one time or genre.

3. How did you learn the guitar, acquire your skills?
I had informal lessons for an hour every week for about three and a half years.
4. Explain your experiences as a female guitar player. (Eg. Finding a band, concerts, stereotypes, going into guitar shops…)
I've never been in a proper band. I've jammed with people a lot, but it's never amounted to anything concerte. I've never really had trouble finding people to play with. A few of my friends are musicians but we've got very different tastes in music.
I had a music teacher in secondary school who didn't expect any of his female students who played guitar to progress past open chords, a male friend of mine assumed I couldn't do hammer ons and pull offs and that I didn't know any scales.
My local music shop is owned a woman. Most of the staff are male, but for the most part they're pretty approachable.
5. Do you ever feel discriminated as a female guitarist? What are the advantages and obstacles of being a female performer?
Not really. Boys are more willing to talk down to you. I think it might have something to do with feeling threatened.
Advantages: You stand out more.
Obstacles: It can be hard to make people take you seriously.
6. Do you think female instrumentalists are still marginalized in comparison to male performers?
To a degree. Like I said above, it's hard to be taken seriously. All girl bands are seen as a novelty and female musicians in all male bands are usually seen as token members.
To young children, rock music is seen as a predominantly male thing, so more boys than girls take it up. A lot of the girls I know who play guitar start playing at a later age and don't intend to progress very far, they just do it for fun. Boys, on the other hand are more competitive and think they have to be better than everyone else.
There are a lot more female musicians and bands in the indie scene than there are in the charts but I'm not sure if that's going to change.
