OP, I know you probably won’t your first time to be special, but it will be special, because it’s your first time, and with your husband.
The thing you’ll learn about sex is, there’s rarely a perfect time, Other than now. There will always be laundry to do, work to do, kids that might wake up, the extra 10lbs you feel crappy about, sleep you wish you were having, etc. It’s easy to put sex on a back burner.
