How about pushing him down on the bed and telling him that all this gun talk is getting you hot and bothered and nothing turns you on more than a man packing heat! That'll get him motivated!
All comedic value aside, I don't want to be manipulative. It's a decision he has to make for himself...I just don't want it to hit the back burner and be forgotten. I really want a way to keep the subject open, without being pushy or belaboring the topic. I'm just not finding a good way to do that without seeming like I'm harping on it...which I definitely do not want to do.
