Husband not finishing

My husband has been really struggling to cum the past month or so. He hasn’t lost his sex drive, he just struggles to finish. We think he’s just been getting in his head because he’s had a ton of stress lately.

What typically happens is that he’ll get really horny and initiate things, do a fantastic job and make me finish, but then he gets soft and isn’t into it anymore. We’ve figured out that I can just suck him off at that point and it’s fine. I just think we’d both enjoy it more if he could cum during sex like he used to.

What are some tips I could do in the bedroom to help him let go of everything else and just be in the moment with me? Or any sex tips that would feel so good to him, he couldn’t help but finish 😅
