<human>: Give me a shortened version of the text

So about 6 months ago I met this girl at work, and I grew to have a huge crush on her by the end of the semester. One day I decided to message her and she gave me her number without me asking! I was so excited, it turns out she's had a big crush on me as well. 

We've been talking for about 2 months now, and dating for well over a month. We've spent a whole day together, went on several dates, and are constantly making plans to see each other again. The whole time spent together is laughing, smiling, and there's no dull moments. We share a lot of common interests, and life goals, so we're very compatible. This whole summer she's been in one town and I've been in another, so it's been a little difficult. But here in about 3 weeks we'll be living only 5 minutes away! 

We are taking things slowly, she mentioned how she had been pressured by past flings into sex early on and how she felt like that was all they wanted. So I haven't made a sexual advance yet, only kissing and a little groping. But the tension is building and I really want to make a move! I'm just worried about doing it too early and scaring her off. 

So I guess the question I'm looking for here is, how do I know when to ask the exclusivity question? I'm crazy about this girl and have no doubt in my mind I could be in a relationship with her, but I feel like a little more time to make sure she's on the same page wouldn't hurt anything. Should I wait until we're sleeping together? Should I ask her before hand? I'm a clueless boy confused by hormones and can't make a decision! I don't want her to think I'm disinterested and playing her until I "get what I want", I want to be in a relationship. But at the same time obviously, I want to be physical with her. I've moved too early on the relationship question before with other girls and learned my lesson on jumping the gun, help me get this one right Reddit!
<bot>: I really like the girl I'm dating and can see us in a relationship, but I don't know when the right time to ask the exclusivity question is.
