How can I ask out a girl in class?
I have no idea how to start a conversation with them, what if I get the number and they don't respond? Won't it be awkward seeing them in class every day for a year? Won't I feel like a failure???
Detailed answers please

Feeling like a failure? Only the girl will know that you'd asked her out and she's either going to say yes and you can probably take her to bed or she's going to be flattered and decline to go out with you.

You're just some guy that asked her out, she doesn't know you. Read this to get over that fear.
