<human>: Condense the text into a few key points

So, my wife and I have been married for three years and been together since high school.  I still love her, more and more every day in fact.  She's very loving and caring with everything she does.  

When she was pregnant neither of us were really interested in having sex, it freaked us both out a bit.  I was in the room when she delivered but I didn't actually see the crowning or anything, I stayed by her face at her request.  

Since then, we haven't had sex.  Neither of us have brought it up, in fact, until a couple days ago.  I mentioned it in passing when we were watching TV.  She asked if I wanted to have sex, and I just said "no, not really".  

As far as I can tell neither of us are unhappy, but my buddies tell me that something's got to be wrong if I don't want my wife anymore.  She's pretty much back to pre-baby weight, still beautiful.  Could this potentially mess with our relationship?
<bot>: Wife and I haven't had sex since our toddler was born, and neither of us really feel interested in trying to start it back up, but I'm worried if this could impact our marriage long term.
