Not bi because I haven't been with a female sexually?

Someone told me in not considered "bi-sexual" because I haven't been with a female sexually. I've been extremely attracted to females since I could remember. My first female crush was in the 4th grade- I turn 20 this year. Growing up I've always denied when people (aka family mostly), asked if I was gay or liked girls. But if someone were to ask me today, I would obviously say yes, because what's there to lie about lol. But I've never announced it and do the whole "coming out of the closet" thing or half out the closet lol. Whatever. Any who. I feel to keep my love life private (unless I, myself, share with people otherwise) until I'm comfortable with that person to share with my friends & family, regardless of their gender. But some quick info with me before I get to the point. Growing up I was dressed as a boy. Pretty sure right out the womb I was dressed as a boy. I asked why they would dress me in boy clothes. My mother said it's because "I looked better that way". It suited me I suppose lol. So pretty much growing up I wore boy clothes. I was considered a tom boy all my life. Freshman year I started dressing a little girly. Blah. Blah. Blah. I even til this day still own/buy male clothes. Just because the comfort. But I do dress feminine some days I guess..

People say they are born gay & I agree with that. But I believe somewhat I was made/shaped that way just because the whole dressing like a boy thing. Growing up being dressed like a boy, made me think I had I act like one etc.. Then it stuck with me.
But now growing up I realize and I feel that I just have a male mentality but born a female. But I would never do the transgender thing, nor am I against it.

Here's the thing with my friend saying I'm not bi-sexual because I haven't been with one sexually. Okay first things first she's lesbian herself. She says people are born gay. And that got me thinking... Okay so if people are born gay and I'm not bi-sexual/or gay because I haven't been with a female sexually. What do you call those who are virgins, AND they haven't been with EITHER gender sexually, but dated them. Lol. You get me?
Oh & she always teases me about being "confused" and blah blah blah. But what exactly am I confused about when I know what I'm interested in lol... I don't lie to kick it, you know? Lol.
And she knows one of the girls I was talking to a couple months back & know how strongly I felt about her as well. But I never did anything with her(as much as i wanted to because I respected that she had a gf which is a whole different story LOL). I even met the chick I was interested in, through her basically. But she still continues to tease me from time to time.

My thing is, I'm not just going to fuck any chick or any dude. I'm picky to a certain point & for me to get sexual with someone, I just have to know them first. Something happened to me years ago, so I try to avoid the whole love thing. More like try to avoid people lol.. But when it does come around, and I end up liking someone (which is rare) I'm not against dating them. I'm almost 20 years old, I've never had a significant other. But experienced one male, sexually, years ago. Then that chick came along earlier this year, and to think of it, she was my first legit person I've actually had interest in. But yeah, even though it sounds pretty basic and cheesy- I love a person regardless of their gender. If I like you, I like you.

So my question is, what do you guys think about my friend saying I'm not bi-sexual because I haven't been with a girl sexually? Do you agree with her? Disagree? Why, why not. All that good stuff. Her teasing me doesn't bother me as much anymore like it did in the beginning, but it is annoying when she does say something. I just ignore it. I don't feel like I need to explain MYSELF to her at all, because I know what I'm interested in. But I would actually like to have a good point that I don't have to go down on a chick to be bi-sexual lol. If she were to bring it up again, which I'm sure she will.

Feel free to say anything

 

Thank you all for your input! Lol. I will happily jab my friend in the neck and think of all you wonderful people while doing so if she says another stupid "you're-not-bi-because-you-didn't-fuck-a-bitch" comment lmao.

 

Your feelings for women don't count? Lol that's stupid!!

 

I feel like my friend is just narrow minded and taking that power of being LESBIAN(not saying all lesbians have that mindset). Lol and looking down at "half breeds" like they don't exist. Like one of those "it's either you're straight or gay, no in between" type of person. She goes "well how would you know if you'd like it? The taste, the juices?" Well actually I wouldn't know YET. But each girl is different down there, as well as men. Shapes, sizes, different taste etc. I mean (idk if this personal but I'll share it anyways because I don't care lol) I watch porn all the time, I like what I see haha. I just have yet to "test drive" it.
And about the whole tasting thing lol, when that time comes with me I don't think it'll be that bad(hopefully they keep themselves well maintained). I'm Asian, specifically Laos & Thai. And let me tell you, we have some funky tasting meals that I find delicious LOL. So I mean I don't think there's anything I can't handle...? But we'll see haha
