well, now I met her. She is 183 cm. high, blonde and slim. Only made it to some petting tonight, so I didn't go full Galeniko. Look forward to getting access to the pussy. 
So who's taller, she or you?

(exactly equal in my case, lol)
The way you describe her and the date sounds good.
I don't know what kind of relationship you want, but most "first date fucks" don't last long.
