Differing Desires

My husband and I have been married for only a few months and we are still adjusting to all the ups and downs of married life. We are incredible happy together, but one thing keeps bugging me a little bit.  I have a higher sex drive than he does. I would gladly have sex with him every night, but we both work demanding jobs and he is very tired at the end of the day. I know he desires me, that's not the issue, my problem now is that I brought it up once, more asking him how I can entice him more/asking if everything is ok. So now he thinks I'm not satisfied, which I am. How can I talk to him about these things without making him feel inadequate? The last thing I want is for him to think of sex as a chore.
