I really don't have that option to go out when I'm upset at the lack of sex. My kids are little and they need me here. This is, in part, an excuse and partly truth. In a little while I will have a newborn who is dependent on me for nourishment so I will not be able to leave it at all.
So, for me, the answer to that question is to immerse myself in my kids and let that fill the hole. It is hard to do because my H is one of those people who will want to be part of the action while this is happening and, quite frankly, his presence annoys me when he is not meeting my needs. It is a real struggle with me, can you tell! When I do overcome it I have good results but they are very sloooow. That is, if I am getting crabby but get past it, that is still no guarantee that I will get sex anytime soon. Rather I will probably get it later rather than sooner, or he will 'forget' for another week or so. Me initiating a conversation seems to be the fastest and most effective way to get us back on track.
As I keep saying here, he is actually appreciative of me getting us back on track. I realize that this is something that will need to be dealt with at some point...encouraging him to stay on track himself and not rely on me.
