As a father of 2, the thing that I would stress is patience for the first little while If your wife has morning sickness that isn't going to put her in the mood. As well, my wife said she was WAY more tired all the time during the first trimester. Then as she adjusted to hormone levels it got better and her sex drive increased. Pregnant sex is awsome! No worries over birth control! As well my wife said her orgasims were a little more intense. Some women that aren't that large in the bust rather enjoy their larger breasts. Another good thing about pregnant sex is as the baby bump gets bigger, it forces the 2 of you to be a little more creative in finding new positions which is always fun.
