Feeling Down , Am I that bad in bed now?

So this morning I woke up feeling frisky and asked my husband if I could make love to him. I jump.on top but what I can't get out of my head is his expressionless face, I mean normally he makes them but the last couple of time he's had no expressions and it's has scarred me - not to mention a week ago we had set and he came in less then 10 minutes, not giving me a chance to finish and make up for it during the week. Its making me think am I that bad in bed now after this morning. Even when I was giving him head this morning didn't even get any moans out of him.
