How to get husband in mood???

Me and my husband have a great marriage. I have hardly anything to complain about. Just one thing we both feel isn't right is our sex life.

My husband is very active in his office but as he reaches home he becomes one lazy fellow hard to deal with. I am still okay with the rest of times he feels lazy. Its been two years since we married and we have hardly had actual sex. Most of the times he wants to get away with fingering. Since now we are planning for a baby, I don't understand how to get him to do the actual work. Its depressing that during my fertile days even if I initiate and try to please him he is just not in mood.

Could someone please advice how to get him to do his part?

P. S. he is a wonderful person and seriously I don't have any other complains about him...
