Unfortunately I'm in the nada club as well though I'm seeing a slight increase in the urges.
With DD#2 my sex drive was insane, probably at least 4-6x a week (it's about 1-2x a week when not pregnant). And that was through the entire pregnancy.
Poor DH keeps trying and I'm just not in the mood. I think he's remembering howt he last pregnancy was and set his expectations high.
Orgasms were MUCH more intense and I truly felt the plentiful amount kept my uterus well toned (experienced lots of BH's after orgasm) and along with the RRL tea helped me in labor (DD's entire birth was -7 hrs, all stages).
