hey there,
ok, number one...never try to make a guy like you...it'll never work, trust me i've tried. Number two you're only 15..you've got tons of time ahead of you for dating. theres no set age for anyone to start dating. But if you really want a guy...my advice is just be yourself....when you start talking to guys just be yourself. hope everything works out for you and hope i was a little bit of help.
Best of luck to you!
