Hi askseddit, first time posting here, so let's get straight to it.

I am 18 and had my prom 3 weeks ago, the night was great, got 4 K-closes and my female friend talked me into messaging one of the girls, we talked on the bar for a while and seemed to get a long, so I said why not. Made some small talk, discovered she's going to another prom (2 weeks ago). That was kind of good and kind of bad. I didn't see it but her sister told me that she basically acted slutty around some dudes, but that night I got a taxi ride with her and her sister (yeah they're twins, not identical, but it's somewhat weird). Made out before the night ended and during the taxi ride... alright now last week it was better, we enjoyed the night as usual but sometime after midnight went upstairs to a balcony... We started making out and time went by and it was half past 2 am and the prom was ending, I tried escalating while making out but she stopped me, well I don't complain really, since she's 16 and I am 18. She asks if I wanna go with them again, so we get a taxi ride and yeah it was just hot.. I didn't try to go with her because of her sister, it just feels weird.

So since then we chatted a lot more, I asked her what she liked the most about the prom and she said the show and something else, I say that I wonder if we mean the same thing and she says she hopes I do. So I say something along the lines of we can have a nice evening during the winter break, she asks what am I thinking of and I say a dinner for example, which she says would be nice.

When we chatted she said what she'll be doing on the weekend with not having any plans on sunday. So yesterday I asked her out on Sunday, which we ended up re-scheduling to Saturday. We agreed to get some pizza in the evening.

Now I wonder, how should I approach this? It's my first time seeing her outside the proms, not being drunk after a few hours and so I seek some advice. Wonder about kino, should we hold hands when I pick her up or is it too needy? My place will be free after in the evening, so should I try inviting her to my place to watch a movie maybe? I guess she'll have to go home because of her mother. If that is the case I will end up walking with her to her place, where I'll go for the K-close, right?

What should I look for, what should I do or not do? Some topics to talk about in general? I guess I won't have problems with this but just in case some safe topics to not have the weird silence. I've dated girls before, but with this one it feels weird thanks to the prom experiences... Also how often should I chat with her? We chatted everyday since monday I believe, today I didn't text her since 11am and it's 10pm, I feel weird not texting her a good night or something, since I texted her everyday now, on the other hand I don't want to make it seem too needy.

Sorry for my english, it's not my first language, thanks for every bit of advice you'll give me!
