Hey lesbians! listen up!
You have a crush you wanna ask out but cant bring yourself to do it.
That's not a question I know you do and here is how -
Tell her "You should take me out for coffee sometime." That's also not a question its a statement. If she sounds non-committal you can back out a rejection because you didn't actually ask her out.
Now on the off-chance she sounds interested here's what you do, you try and set a place and time right then. Don't pressure just see if she'll commit to a place and time. If not once again you can back out real easy with just a "Ah well you can text me later." Leaving the door open but the pressure off.
That's how you pick up chicks without asking them out you're welcome.
