am i picky? or closed? or shitty? or just want something a little less "modern"?

so, this video store dude. he seems nice and all, but within the first 5 minutes of TEXTING it was about sex. this makes me think he doesn't have anything else to talk* about. and then, subsequent TEXTS (why he can't push the "call" button on the phone and talk to me, i don't know) are just in the "what are you wearing" vein and i'm so over it already.
i saw this guy for maybe 5 minutes, at the video store, and since he was impressed with my movie choice of "dead snow" (fantastic zombie movie) and my ability to speak articulate and coherent sentences about something he likes (mainly because i was around people i'm not attracted to) he just latched on.
from what i remember, i KNOW he's shorter than me. kind of significantly. he's covered in tattoos almost in the way that people cover themselves in tattoos just to show others that they're covered in tattoos and are, therefore, "badass". he's got 2 kids. and he can't find anything else to talk* about except sex. he couldn't (maybe wouldn't?) even expand on movies and his favorite ones or favorite genres or anything like that.

people say i need to "open up" and let people in and what not, but accepting this, settling for this for even a small amount of time is not what they mean, right?

* - texting is NOT talking
