Is it sad that I've never had a REAL boyfriend or dated and I'm in my last year of high school?
REAL = Someone you can go to REGARDLESS of anything, they want to be with you mutually not just sexually, emotions highly involved, etc.
I have had a few of those play boyfriends when I was younger, but of course the word dating was forbidden for children our age, but now that i'm in high school, i am never really asked out, sought out for, wanted, etc. I understand that most kids my age are only 'hooking up' and whatnot and are not out for anything committed, but I would like to experience love. I don't have a good family relationship, and my friends are there, but they have their own lives to live…. there have been guys that confessed that they like me emotionally and others that like me JUST physically, but they are guys that are already taken or looking for an easy girl to bang.
1.) What should i do? (I am a plus size girl, but I'm always complimented that I'm cute -never ugly, just overweight-) I believe I am not ugly, but i am a bit shy yet still outgoing and could care less to what other people say.
2.) Could it be because guys see me as one of them? (I wear girly tomboyish/goth clothing and a lot of my friends are guys)
I have been asked out on a date, but that's from a guy that was just too obsessed with me and immature…. -he told me it will be sad if i go to prom by myself and isn't asked out, so…is that true too? 
3.) Is it all just because I'm overweight? Or am i asking for too much for such a young age group?
You sound like me back when I was in high school in terms of not having a relationship/boyfriend. My first (and current) relationship wasn't until about the middle of my senior year of high school when I was 18 (I'm 22 and a college senior now). I'm also "plus sized" (I just say fat), somewhat shy but can be outgoing when the situation calls for it, and dress goth/tomboyish (unless I'm going out, then I do dress feminine), and I think those were all major reasons why I had a hard time getting somebody in high school. The few guys that did express any interest in me were guys that I had no interest in and I know were probably just looking for sex. I ended up meeting the guy I'm with now on myspace actually back in late 2005, and now we're engaged and live together, so I guess it worked out in the end (now, if I'm currently happy in my relationship, that's a different, complicated story, but at least it's a relationship).
Anyway, I still don't get much attention from guys, although maybe that's because I have an engagement ring on now. I know in my college years there's been at least two guys I suspect that had an interest in me until they found out I was engaged, so I suppose the ring could be part of it. I also did cheat (thought I had permission at the time and that it wasn't cheating) once on my fiance with a girl, but the girl has really low standards, so that's not saying much.
But getting to your points:
1. I'd say if you're 18, of if you're not yet, when you are, set up a profile on a dating site, like okcupid. It'll help broaden the scope of guys and won't just be like ones you know from school and would give you better chances of meeting someone. Even though I'm big myself, I have a friend who's a good hundred pounds more than I am and I know she's met several guys off of there (then again, she's 23, so there might be more people around that age on a dating site than people who are closer to 18).
2. Could be. Like I said, I don't really dress that feminine (a typical outfit for me, for example, would be like a Bauhaus t-shirt, plain black pants, and boots) and I know no guys pay attention to me when I'm dressed like that. When I go out to parties, bars, goth nights, concerts, and so on I dress a lot more feminine and wear corsets or another type of feminine blouse and on occasion skirts and more make-up than I would in an everyday setting. I notice when I do get hit on, it's when I'm dressed kind of slutty. Not that I would recommend dressing slutty, but having some slightly feminine touches would probably get you noticed more and make you seem like less "one of them" to guys.
3. I'd say being overweight contributes some, but it's certainly not the only reason. Especially at a high school age, yeah, some guys are going to be superficial and absolutely would not date a fat girl, so that does leave less guys to choose from. But there are plenty of guys who don't care if a girl's fat or not, so it's probably more than that.
I don't think so but if you do, then it's sad. Actually, I think its smart. Do what you have to do to get a career and worry about your plus size later. Also, if you wait a few years, everybody will be plus sized.
i think you should wait until your really love comes to your life
Advise: Dont look for Love Wen its meant to be it will come to You….. If your a tom boy then be a tom boy don't change the yourself… You might grow out this stage and you might not but just be yourself………. Trust e you will get over it because its just a pharse….. Next time you like a guy just go 4 it…
Good Luck
