My Ex... was the same except all desire stopped after she became pregnant with S3. Frequency was once every 6 to 8 weeks. After he was born it got worse. Once every two or three months.
But it was not me. My previous post D girlfriends had no complaints.... It was just that Ex was out of love for me. She had this assumption that the baby would make her fall back in love with me. It didn't.
Funny how her libedo came back 2 weeks after we seperated when she met her current boyfriend of 2 1/2 years
