I just started getting to know a girl, that I’m interested in, but I don’t get to talk to her very much, since she’s always working most of the time, when I see her. I’m thinking about asking for her phone number or Instagram account, so I can stay in touch with her? Which one would be better to ask for?

I was 17, at a football game. There were 2 girls there. One of them put a hotdog into her mouth, asked me to take a selfie with her, then the other asked me "are you gonna j-ck off to the picture of [girl's name] eating the hotdog". I stammered incoherently because I was caught off-guard. They then kissed me on the cheeks.
A couple days later, the girl who had asked me about j-cking off sent me a picture of the girl who had eaten the hot dog on snapchat, captioned, "she wants to suck your p-nis". I snapped back a thumbs up that was captioned "nice".
A few days after that, I had a huge snapchat story, and the girl who had asked me about j-cking off said "that story was almost as long as your p-nis". I said "yes, it was"
