I feel like such a loser everybody I ask out says no what should I do

tu shouldn't get upset. If they don't want to go out with you, it's THEIR LOSS! They're obviously missing out on something pretty great :D
And trust me, when the right person comes along, they won't turn tu down. I know this is super lame and overly cliche, but I live por the quote "Everything happens for a reason." And maybe it's a good thing they turned tu down, so tu can be single for better and bigger opportunities/people. :]

Plus, dude how old are you? 13? tu have your WHOLE FRIGGING LIFE to find "the one." It's nothing to get majorly upset over. Trust me.

don't worry. One día the right person will appear.
BuT i NEED tu TO UNDERSTAND THAT REAL BEAUTY COMES FROM THE INSIDE. Hope I helped ^^
OH and if tu need to talk I'll be here

ok first of all, stop crying...is it really worth crying cause a couple of boys wont go out with you???really??
second, tu are 13, right?chill...you dont need a boyfriend yet...and even if tu do, why dont tu just wait?i find kinda lame when a girl asks a boy out.
still, even if a boy doesnt want to out with you, that doesnt make tu a loser...

and generally, what is that obsession with everyone to have a boyfriend/girlfriend?? it doenst make tu any "cooler" o so...seriously...

Don't ask anyone out, unless your 100% sure they'll say yes.

dont worry there is somebody 4 everybody and 1day your going 2 meet the person of your dreams and these idiots who dicho no youll forget them

4 Words, Amariacn Guys are Wired

LET THEM ASK U!!!!!!if they always say no then wait for them...

My friend thats a guy told me that its bettr 4 them 2 ask u out if that helps, plus, anybody thats stupid enough 2 just want blonde binbos & not real ppl thats there loss

Personally, I think boyfriends are overated. Heck, a lot of my friends have boyfriends, but they also have a lot más drama in their life because of it. I can make my own stress, thank tu very much.
Anyway, though, you're not a loser just because a couple guys dicho 'no' to you. They're probably not your type anyway, so to heck with 'em! I could think of worse things. I know someone who went out with a girl who asked him out just because he didn't want to make her feel bad. tu can just imagine how that turned out. So, maybe it wasn't a completely bad thing they turned tu down. At least they were honest with you.
I guess tu could take everyone else's consejos on here about waiting for them to ask tu out. Be warned on that, though, sometimes the guys who ask tu out aren't the ones you'd expect o even want. That's not always a bad thing, though. ;D And in the meantime, don't worry about being single. Trust me, being single has many advantages.

Make friends with the boys tu like. Wait for the boy to ask tu out.

*sigh*, another relationship issue...

dude, you're only 14! tu still have like 16+ years to find someone, get over it and focus on school instead! I'm older than tu and I don't ask guys out(nor will I ever, I believe that guys should ask girls out). Point is, don't worry about it, enjoy your life being single, when the time is right, something will happen but at 14, it's still way too young.
