How do I convince myself I'm a guy?
I dont like wearing girl clothing
I dont like fawning over boys
I do kinda want to dress like a dandy
The girl I like will feel more comfortable with me if I can accept myself
I feel like a guy and think like one I dont look like one or act like one
I just want to accept myself and the only way I see to do that is to convince myself
I cant cut my hair either... 
I ment sexualy not gender-wise

I'm not sure what your biological sex is. But if you have a penis, look down and there you are. That is pretty good proof.
If you do not have one, then it really depends on you. Transsexuals feel that they are a sex different than the one that nature assigned to them. If you feel this way, then you are absolutely a guy. Nothing wrong with it and there are plenty of others out there who feel the same way and disagree with their biological sex. If you are biologically female but feel like a male, then you don't need to worry about doing "masculine" things. Since you know inside that you are a male, it will come naturally to you. Males don't need to be "macho". Just be yourself.
However, if your biological sex is female and you don't feel like a guy, why try to convince yourself that you are? Be happy with who you are. Believe me, transsexuals don't say, "I feel like a different sex" for the fun and acceptance of it. If you think you are your biological sex, be happy with that. Transsexuals are one of the most discriminated group of people in the world.
Don't feel forced to be put into a gender box. Just because you don't feel like girl doe not make you a boy. Some people don't identify as either genders. Gender is socially constructed and is not a part of you. Be yourself find what makes you most comfortable even if that is taking the best of men and women. Never change who you are for another person only you can make yourself happy. Good luck i hope it all works out enjoy
Transsexual-when a person's biological sex does not match up to their gender, and (most) transition and get a sex change to live the life they're normally supposed to have. I am a transsexual male, meaning I was born female (with female parts) but my gender is male. Sex is between your legs, gender is in your head.
Transsexuals KNOW they are transsexual, usually at a very early age. It's been hardwired into my brain that I'm male. I have already started transitioning, which I've wanted to do for years. I don't need to "convince myself I'm a guy", I've always 100% known. So, with the way you're wording this question, I don't think you're a transsexual. I think you're in the category of transgender, however.
Transgender-an umbrella term for anyone whose gender identity does not match up with their biological sex. For instance, there are androgynes (they identify as beyond gender, genderless, intergender, etc.)
Then there are even people who consider them both genders. They could feel/act female one day, then make the next. (This is known as gender fluid)
Some people don't even see themselves as having a gender.
Do you feel like you're a man trapped in a woman's body? Would you consider a sex change in the future? If not, you aren't transsexual. Especially if you have to convince yourself you're a guy. To me, not to be rude, you sound like you're a lesbian with a more male attitude. (Like a "butch lesbian).
If you're having serious gender issues, then see a gender therapist. For me it sounds like you're having more difficulty over sexual orientation. Remember, sexual orientation and gender identity are COMPLETELY DIFFERENT. Do a little research and see what clicks. You don't need to convince yourself you're a guy. You just need to dig deep and figure out how exactly you feel. Genderless? Bigender? Genderqueer? Only YOU know who you are.
You can still cut your hair, its a choice not life. You can act like a tomboy if you want, it turns the girly girls on sometimes. You don't have to completely act like a guy, you have the excuse of being a girl to act like one. If you want to convince others that you're a guy, then that is different and would disappoint the straight girls too.
If you have to convince yourself that you are gay, than you have not truly accepted this.. maybe you need to work on accepting that it's okay, and not to place judgement against yourself in anyway.. this would be a start )
Grow facial hair or grow up some more.
you take a long hard look at vagina and say No Bad
look in ur pants. if theres a penis then ur a guy. oh sorry ur a girl i didnt know.
