Not enough time for sex?

Da

My fiancé and I are working our asses off right now to save up money for something. This means ten hour shifts plus a 1.5 hr commute each way. When we get home we’re usually so tired that we just fall asleep. Then the next day we have to get up super early again.

Right now we really only have sex on the weekends and I keep missing my fertile window I think.

Anyone else have this problem? I know it only takes one time but our chances are so slim that way.

I’d be up for it after work, but he works a physical job and just doesn’t have any energy left at night.

What to do?
