TG and I are in the exact same situation. I have a fulltime job and we have a 16 month old daughter. We also have other goals and obligations like his work in the Subbie Task feature and my writing as well as the day to day things like laundry.

We try and often fail doing anything BDSM related but we do the best we can and are thankful for the little bit here and there that we can get. We just basically have to realize that life cannot revolve around BDSM 24/7 as much as we may want it to. "Real" life interfers more often than not and we just keep up the hope that we will eventually be able to do more together.

Another alternative, perhaps, is have him do things while he is away, just so that the thought and the mood is still there and you still feel like you have some sort of control and he is still doing something to please you. It could be anything, really, from wearing (or not wearing) something specific or doing something each night before bedtime and then having him report to you on what it felt like, any hurdles he had to overcome... or have him keep a submissive journal for you to read when you are together. Just a few suggestions.

Just hang in there. It's tough I know, but the little bit you do get is worth the wait and perhaps you will be more able to be more vigorous in the future.
