Since your husband tends to be more on the conservative side, it actually takes more thought AND effort on his part to bring your sex life up to the level that you desire it to be at.
For you, it comes a bit more naturally it seems, but for him...Not so much.
So while he has been trying to make an effort on his part, he also has had his own distractions off + on, primarily his new job training and being out of town.
In other words, he has had to focus his attention on his job right now so he hasn't had much time to focus it on anything else at the moment.
Give him some time to get settled into his new job and to the point where he can start again to focus some of his extra-curricular energy back into your sex life.
Again, this stuff may not come to him in a natural sense so it will take some time and patience from you.
It sounds to me like he is trying to make the effort on your behalf, he just got a little distracted on the way w/this new job.
I say, give the guy a break and support him rather than get impatient w/him.
Good luck to you both.
