How to date a nerd guy?

I'm 29, my boyfriend is 34. We're both nerds. We both enjoy anime and gaming. However, when we meet up, all he wants to do is watch tv. We're together for 3months and sex is off the table. I tried to spice things up and attempted to give him a bj and he freaked out. He's not a virgin and I don't understand what's wrong... I have tried to talk about but he's happy to be glued to the tv. Should I call it quits?
