I am looking for advice on how to handle this situation.

Sunday mornings are the scheduled sex time. It's the routine, it plays out the same way over and over with minimal change... One sided and not much enthusiasm.

I went from an on and off dead bedroom kind of situation to what I think was a hysterical bonding episode, which came after I stated that I was miserable and that I didn't even think I could even be happy with my wife. She broke down and then turned into a nympho for like 2 weeks. It was sex all the time, waking me up at night, random make out sessions during the day...like a total 180 flip. Well in that time she recommended making sure we had sex twice a week, which I was like hell yea.... It cooled off pretty fast though and then once a week was the newly negotiated situation and it's been that way for around a year.

Is this routine going to hinder my long-term progress? The uncertainty of if or when sex might happen has been a source of anxiety for me in the marriage.

So do I stop the routine, deal with the potential dry spells and rejection, or do I keep the routine and try to add in more attempts throughout the week? Is scheduled sex a bad idea altogether?
