dont lie and be yourself
if you have to ask that just reframe from considering it
Make her feel like she was your first choice and ask her as if she was.
That is not right
the same way you ask out a girl that dont have one
A romantic way to ask a girl out on her birthday would be to take her flowers and ask her in person.
a guy should ask a girl out a girl should never ask a guy out......:D
Ask her. There really is no other way.
Ask her if she wants to do lunch.
You talk to her first and get to know her then ask her when the time is right.
Be creative.
The same way you would ask any other girl the same thing
The same way a guy would ask out a girl approach her and tell her that you like her if she is straight then she might not be interested but you never know till you try.
