How do you open up a line of communication? I'd start with the suggestion that he turn the game off just long enough to have a time to talk. Then with his attention, be candid. Just say that you have concerns that you feel there is not enough 'touch' - not necessarily sex but touch. Then hopefully the two of you can get on board with some good relaxing touch - massage. Then make him feel good. You want to touch him, do it, and turn him on. And yes, oral is an awesome way to.... touch. Hopefully he'll reciprocate. If he doesn't respond to that... then, I don't want to say you have a real problem, but you have more to deal with that may be more challenging to answer.
