Is This Okay? (BOYS)?

Im a boy and im 16 years old and i was wondering, is this ok? or like what do you think? MANY/ALOt of people tell me im very goodlooking and handsome but once my mouth opens you dont wanna talk to me. I come off snobby, rude and stuckup to many. Ive had a troubled past in school MANY years back like elementary and middle school with this rumor about me sayin im gay and people would tease me, but because the rumor is partially true; im bisexual, im constantly on my guard and alwys defensive, even to people idk. like its so hard for me to meet someone cuz i will automatically think they have a problem with me and even people who gave me a hard time years ago, they've grown, left it iin the past and try to be my friend now but i cut them off and i end up being so rude. I just realized this and many people tell me and now ive started to realize its not all about the looks; im always complimented on how cute and goodlooking i am but underneath that good looking person has an ugly personality. I always want to be in control and take the lead when im with people, would you still date somebody like me for being this way?
