I always think if girls thinks that I'm gay is because I act like one...
For god sake, Stop talking too much and stop touching her...But that just me, and it fucking work too.
If we don't know how to be a man, then of course they would perceive us as a gay.
Here is my 2 cents:
Just shake hands,introduce yourself,tell her your intentions, something like, "I want to spend my time with you in a romantic way", then instant date, or get her number and get off!
No matter how little your first interaction with her, there is no way she is gonna flake if you seriously tell her that you want her. If not, she
will reject you right away.
If some girls still thinks that this sweet beautiful approach is gay, then I am sure she is a fucking lesbian.
