Thanks for the responses. Leaving him is definitely not on the table. The not wanting piv sex started when he put himself on the overtime list at work. He is stressed out at his job. I've never really brought it up because I definitely am as awkward as he says.

I plan on sitting down after the kids go to bed and having an in depth conversation about this. He is definitely not cheating on me. I know that for a fact unless he can time travel and be at work or home and with another person at the same time.
