Be prepared for more bibs, more vomit, about the same amount of diapers, and a lot more crying. At least that’s what I gather from the mommy blogs. Now, since you didn’t ask how sex will be different for her, I’ll assume you want to know how it will be different for you. That’s good — I’d hate to have to try to summarize the varied and endless psychological, social, and sexual affronts that your wife will experience through this black deed.
You, on the other hand, might feel something like a mildly annoying bump. That’s because some degree of tearing usually occurs with a vaginal birth, and “if the woman had a lot of stitches that were put into that area, the man might feel knots or scar tissue,” says Dr. Brad Douglas, OB-GYN at St. Mary’s Hospital in Richmond. This can usually be remedied quickly and painlessly (for you) with a steroid injection. The other thing you might feel is the feeling of not feeling anything. Many experts in the field (thanks, guys, next round’s on me!) report that a woman’s body is a “whole new landscape” after giving birth, which I’m going to guess is more like a shifting sand dune than an active volcano.
Kegels — pelvic-floor exercises, which you may Google at your leisure — can help tighten her back up, so long as she does about 200 a day without fail. You might also want to invest in one of the insertable biofeedback mechanisms available online. There’s one called Intensity that goes for about $150 and might not hurt too much when she throws it at you.
