So, I just got a girl's number at the gym and I'm not sure how to proceed. This isn't my first date ever, but to be frank I've never been very good at dating. I can get girl's numbers no problem, but once I start dating them they lose interest, fast. So here's the back story. I've seen her every day at the gym for the past 8 months (I mean 6 days a week, 2 hours a day), so I've seen her every day. Initially I wasn't that attracted to her but it really grew over time, and I talked to her the first time a week ago, we had a friendly 10 minute talk and went on our separate ways. Today I approached her and had another 15 minute talk and at the end I said I had to get going, and then asked if she wanted to get coffee. She said sure, and then she said "actually I don't drink coffee" and I said "ok, give me your number and we'll do something, not coffee" and she did. So essentially now my problem is this: I don't know what to do for the date. Should I ask her to dinner? I've been told that's too forward for a first date, but coffee is out and it's freezing in canada so a walk is also out. Really not sure what else there is, movies are terrible cause I want to talk to her.

Also is it weird to kiss on the first date? I've not done it as a rule in the past but I once asked a girl why she didn't want a 2nd date and she felt I wouldn't break the romantic barrier... I just thought chicks didn't do that, maybe I'm really living in the past (I'm 23). Anyways any help would be great!

Edit: Thanks for the replies, although many of them are contradicting and all around confusing. Basically I've narrowed it down to two choices: museum or rock climbing. I like both a lot, but I don't know what she likes. I know she likes fitness (gym 15+ hours a week) but no idea about nature... But everynoe likes nature?
