Depleting sex drive?

Crystal

First post here—- please be gentle. I’m 32 and my current SO of 7 months is 38. We started out hot and heavy. It was amazing. The last 2 months... nothing- unless I start it. He says it’s his age and his depleted sex drive blah blah blah- I’m not looking for compliments- I know he is pretty damn lucky to be with someone like me SO- is this really a thing or something else?

Full disclosure- he is a single full time father who has a full time job and house hold to run- I know he would never cheat or anything like that. Just need some guidance
