Is it possible that your DH is not trying to punish you for coming home late, but choosing a safe time to tell you that he does occassionally experience sexual feelings? Also, coming from the perspective of being the lower desire spouse, is it possible that he feels too much stress about your sexual relationship and finds the cuddling to be most comforting or a stepping stone right now? As an outsider, it appears that the cuddling and kissing are a good thing and I hope for you that he is trying to find his way to engage in a more sexual relationship.
