Probably TMI, but...
Since DH and I have been together, we hadn't before gone a week between DTD. Even if we went 3 or 4 days, I would have an O in my sleep.
So, one week before the birth was the last time we DTD, and then because I had high BP and we were trying to fix it before the birth so I wouldn't have to go to the hospital, we decided to avoid doing anything sexual that might trigger labor.
A few hours before I went into labor, I had an O in my sleep.
Twice in the first week after the birth I had an O in my sleep. Now the baby is 3 weeks old and I haven't had any more.
I have been giving DH lots of oral sex, but I am definitely not ready for vaginal sex. When I feel down there, it is creepy.
