Just did this recently with DH after we'd spent months trying to organise our work schedules to allow us the chance to make it happen. I had been wanting to try sex during the day as for many years, we have only ever had sex at night. We have never really had the chance to do it during the day as we are always busy working or looking after DCs. I had been noticing myself feeling especially horny during the day, which also contributed to me wanting to do this.
We finally made it happen earlier this week and it was wonderful. It was probably the most passionate sex we have ever had. We are in our 40s and have been married 16 years. We were all over each other as soon as we got through the front door, and barely made it to the bedroom with our clothes still on. I couldn't stop smiling for hours after it happened. DH said he feels the same about it. I am hoping we get the chance to do it again soon, although it probably won't be for a while.
