So me and this girl have been talking and she said she'd be willing to mess around. I asked if I could come over and she said yes. But the problem is I dont know what to do or say once I get there. I mean I can't just come in and be like, "ok let's do this" and start kissing. I just wanna set the mood so we can do this in the future. So what do I do/say once I actually get to her house?
