I'm 20 and haven't fucked a girl before. Today I got a girl (probably 6-7/10) to come over to my place, we watched a movie and then kissed/made out and dry humped each other. I have a few questions.

What is the best way for me to approach plating her/having sex with her? I understand just asking her to come over through text, should I suggest we make dinner together this time? Also she gave me a hickey, its not very large, is this acceptable behavior from a girl? Not sure what to think about it, didn't even realize about the hickey until later.
