been dating a guy, how long to wait to be bfs?

I've been seeing someone for almost two months and going on "dates" about three or four times a week. After about the 8th date we got "intimate" and have been since then. We are both in our early 20s and both of us has only been in a relationship once prior. so we are no experts :). we are both pretty nerdy guys although i give off more of a jock look i feel really attracted to him which he has a very nerdy look to him which i like very much :) we had our first kiss in public after having dinner and walking him to his car early on when we first met. i've spent the night over at his place around 5 times and met his roommate. I am very insecure when it comes to reading peoples feelings and emotions so i never really know if someone "really" likes me. he's not really a big "texter" which i've come to learn and accept because at first i just felt he didn't care much to talk to me but after being around him so long he rarely ever picks up his phone often just every now then, but he'll still text me throughout the day to see what I'm up to. we both have opposite work schedules but we somehow get to still go on our dates. This past week he texted me about going for a walk around our local college area and ended up watching a movie cuddling and holding hands during the movie. i told him i wanted to take him to a small town a couple hours outside the city for his day off so we could spend it there and he suggested we stay in a hotel so we could spend the night and cuddle there. What i really guess i am wondering is when do or should we talk about the boyfriend subject? is it still too new? am i over thinking it? how long did it take you to go from dating to bfs? also does the long times to reply to texts just me over thinking? have any of you been with someone who is not big on texting? I'm not really big on texting either i just enjoy talking to him that i like it when he's texts me (selfish and guilty).thank you in advance for the replies and suggestions :)
