I am 29, have been married for 7 years. We have a quite happy life with its ups and downs.
I do want to have sex at nights, he wants it in mornings. I need it one night, but he doesn't feel like getting into it. Sometimes I awfully feel I am sexy but he is not home. Or when he comes it's night and I have to wait till next morning. What should I do?

Buy a vibrator.

My husband has ALWAYS preferred mornings for sex.

I feel bad for him, because I simply can NOT wake up enough in the morning to oblige him.

For special occasions, I've set the alarm 2 hours earlier than his just to give him that special sex, but frankly--getting up 2 hours earlier just for sex never worked for me. Unfortunately, late at night (when I'm more likely to be in the mood) doesn't work for him--he's tired, shut down for the day, just doesn't work.

We worked TOGETHER to come up with a time that worked for both of us. That meant a lot of talking and experimenting with other times of the day. We found one that worked (right after work), and that worked great.

However--you HAVE to be willing to revisit the discussion and make changes when life changes--a new shift at work for one of you, a baby being born, etc. After our son was born, in the morning actually works a little BETTER for me, because it's the only time of day I actually feel rested!

You need to work TOGETHER, with LOTS of conversations, to make it work for both of you.
