<human>: I was fine when she was first pregnant because there weren't any visible signs that she was pregnant, but now that she's showing, I just can't get into sex. The constant reminder that our kid is literally right there next to us gives me the heeby jeebies and is just about the least sexy thing in the world. I don't even know how she can enjoy it because it's all I can think about, and that's a total buzzkill. 

She's upset with me, especially since she is so...ravenous now, because we haven't had relations in a month, but I just can't enjoy it anymore. If I'm honest, I just don't find the pregnant body attractive. I wish I could, but every time we try to get things started, nothing happens. I physically can't make myself want or enjoy this, so it's not even a matter of it all being in my head. 

I can understand why she is hurt, especially since I always decline, but I've told her repeatedly that it has nothing to do with her. Is there a better way to explain this to her?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I don't find pregnant bodies attractive, and I can't physically have sex with my wife. I know she is upset, but I feel like if I could explain it to her in a better way she'd understand.
