My situation's a little different.
But, every time S and I broke up, I was on sabbatical. I really just wasn't interested in anyone else sexually. Literally NO ONE else for long periods of time. There was Hot Coffee Guy, who turned into Couch Crawler Guy that was fun to joke with but it was just that... joking around. For the longest time, I wasn't even interested in my own hand (Mr. Purples don't work for me).
But the difference is that S has been my only partner. He's really the only person I've had an attraction to that I've been willing to ... blah, blah, blah, that's another story.
But, my sex drive waxes and wanes even when we're together. It kinda sucks.
We'll go almost a whole month without intercourse (I really enjoy giving blowjobs, so I don't mind keeping him satisfied) and I'll be okay with that. Which bothers me and I have to make a conscious decision to start focusing on what attracts me to him. I think a lot of mine is hormones. But, I come out of it when I really recenter myself and our relationship.
When we have been separated (multiple times in six and a half years), I almost didn't care and didn't make an effort to try to improve my drive.
Changing b/c pills helped, too.
I think it does come with age, too. Enjoy Mr. Purple. And your sabbatical... until you're in the proximity of another sexual being that you feel like jumping.
