How do you ask a girl to do it?

not really dating, she's been following me for a few month now, and I kinda just accepted her. (My parents don't want me to date or anything though, I didn't tell my parents anything about her, but I like her)

maybe i've watched too much porn, but i really wanna try to do it with her... but i can't imagine myself doing it with her, let alone find a place to do it...

Umm....this is the funhouse, but I take it you're serious. I say take it slow and make sure you think it through before making your decision.
