How soon is too soon to be officially "together" in a relationship?

Asked by missjena (918) January 16th, 2010 from iPhone

I met this great guy through my sister who she has know for her an entire life but theyarent that close. My sister has nothing but nice things to say about him. We have only been on about 3 dates and he already wants to be bf/gf. He is 29 I’m 24. Ido like him; however, why so fast? Do you think it’s too soon?
