It's great that he loves you, but there obviously is a problem.
He is young to have lost his sex drive. I definitely had no issues at 35!
Equally, you are far to young to have a sexless relationship.
I think you need to probe deeper. How has he been through lockdown?
Do you have kids? If not, turn the TV off, and really talk to him - tell him, as calmly as you can manage, that you love him, but that you are concerned about your sex life. (This is tough by the way!)
Tell him you still fancy him, still want him, but you feel that maybe he doesn't feel the same? Explain why.
Do your best not to get angry, upset, or judgmental. Stay calm, listen to what he has to say, and try not to rush into any silences.
Don't be put of by generalities, or off hand comments, push (gently!) for detail.
You both need to communicate - it's not a one way street. If he can't talk to you, would he talk to a counselor?
