Kristen Stewart wants to acknowledge the ''fluidity'' of sexuality.

The 'Personal Shopper' star - who came out as gay on 'Saturday Night Live' recently - doesn't understand why bisexuals are labelled ''confused'' as she thinks it is, in fact, ''quite the opposite''.

She said: ''Oh, I think things are changing. I mean, I don't think I would have approached my life differently if that hadn't been the case. But who knows? Individually we are all part of that change and so I can take some credit for it, I guess - there's no reason why I should shy away from that. But all the prejudice; it's going for sure.

''I mean, yeah, it's definitely still there. People still have some horrendous f***ing experiences. But it's cool that you don't have to nail everything down any more. That whole certainty about whether you're straight or gay or whatever. You're not confused if you're bisexual. It's not confusing at all. For me, it's quite the opposite.''

And the 26-year-old actress is glad people feel more able to talk about sexuality in general now.

She added to The Guardian newspaper: ''That's been nothing but positive. I mean, it's hard to talk about. I don't want to seem presumptuous, because everyone has their own experience.

''The whole issue of sexuality is so grey. I'm just trying to acknowledge that fluidity, that greyness, which has always existed. But maybe only now are we allowed to start talking about it.''

Meanwhile, Kristen previously admitted it took her some time to realise how important it is for her to open up about her private life because it can affect others too.

She shared: ''But considering I had so many eyes on me, I suddenly realised [my private life] affects a greater number of people than just me. It was an opportunity to surrender a bit of what was mine, to make even one other person feel good about themselves.

''If it didn't seem like a relevant topic like something that needed help, I would have kept my life private for ever. But then I can't walk outside holding somebody's hand, as I'm followed everywhere.

''When I was dating Rob, the public were the enemy - and that is no way to live. It wasn't this grand statement, 'I was so confused! Now I've realised who I am!' I have not been struggling. It just seemed important, and topical.''
