I understand completely what your husband is feeling being a post-op husband myself.
Not having a huge stomach and thighs in the way changes intercourse dramatically. One can get in there more completely, which gives much better sensation than before.
Then their the whole idea that he is feeling much better about himself.
Heck, his excess weight was probably a huge motivator in doing oral sex in the first place. He may have felt he was not satisfying you with intercourse so performed oral to ensure you were happy. Now that he is happy with intercourse and feeling like you are both being satisfied oral is less necessary.
Some clear and honest communication on wants and needs may help in understanding the situation. Guessing is more often wrong than useful.
Good luck,
Tek
