problems

Okay y'all so me and my SO have been together for 7 years. He has always had a problem cumming, he could usually stay hard though. We kinda got over that hurdle but since we had our son 9 months ago it's not as easy to have sex whenever we want. I try to at least once a week, I would say he cums usually 1 time for every 5 times we have sex. He tells me he has always been this way during sex. He is EXTREMELY stressed out right now being our sole provider. He works a hard labor job, lots of OT. Didn't even get to see our son yesterday. We had sex last night and he couldn't keep it up. I don't get it! He always gets hard Everytime we touch or hug. He also initiates it, it isn't like I just hope on him and expect it to happen. He reassures me daily that I'm beautiful and how in love with me he is. Could this really be stress? Like he is overthinking the whole thing? I've tried head, he has never been able to cum.from oral. I don't wanna put more pressure on him but like I cum twice. I feel gross like some over eager way too wet too into him and it like I'm the only one getting anything from it. I am really anxious and increasingly depressed from all this.
