Hopefully I don't get flamed as I only found this reddit today while doing my own research but here we go.

My wife has always had a very high sex drive and I would sometimes struggle to keep up. She's almost ten years younger than me so that has some influence I suppose. We hit a struggle point a few years ago and found this love language test that we both took and it shed light on a lot for the both of us. We were able to see why we weren't feeling fulfillment from each other the way we thought we should and although neither of us have changed completely it made a big difference in how we could read what was missing.
My wife and I are in the service and I'm deployed while she's pregnant. Thankfully she's spending the last weeks of pregnancy back home with family so she can be surrounded by comfort in my absence. I found myself here wondering about the sex topic (I'm deployed like I said so she's on my mind a lot). I have done a lot of reading based on our current situation, health, and other factors to try and mentally prepare myself for what's to come and it seems more often than not it's less of a physical mountain top and more of an emotional battle for the woman to feel ready.
Can any mom's and/or dad's give some good tips on what worked for you or things to keep an eye out for? My wife and I are very open when talking and she's brought up more than once that she wants to get back on the horse ASAP. I have a good feeling that will change after birth even if everything goes as perfectly as possible. I suppose I am just hoping to keep her feeling positive about how her body changes and hope (a little selfishly) that things don't slow to a halt for good afterwards.

Thanks in advance to anyone willing to offer some advice or things to read to learn more! (I marked this NSFW because I wasn't sure if the topic should be labeled like that -- just playing it safe).
