My girlfriend lives a few hours away so I'll be honest, when we see each other we mostly just fuck.
But we do still find other things to do:
- Make food together. We can only do this at her place, since my kitchen is tiny.
- Have a bath together. Not "sex in the bath", just a bath, one of you cradling the other.
- Watch TV and/or movies. So far I've watched 1 season of Heroes, 4 seasons of Dexter and a decent number of films with her cuddled up and resting her head on my lap (on a pillow).
- Go outside! You like any sports? Go try those together. Failing that, just get some air. Go shopping together, even grocery shopping - at least it's something you both need (I had a girlfriend once who refused to go into gaming stores with me and actually asked "Does this make my butt look big?" while shopping for clothes - yeah, that ended well...).
- Go to town, visit landmarks, check out museums, art galleries, restaurants and cafes.
- Get him to give you a massage. Give him one. But be warned you may not stay sex-free for long.
- Travel together. It's a great for seeing just how much you can really put up with each other at a stretch, especially when you're tired, lost and grouchy.
Annnnd that's about it from me. See? Plenty of stuff! Good luck to both of you.
