The last few weeks have become increasingly trying on our relationship, and no matter how much I try it feels all my fault. Nothing bad has happened; but for reasons unknown I've become extremely insecure. Dh and I are on different shifts, so we only see each other in passing. On top of that, the intimacy stopped about a month ago. Not because I wanted to.....it just became uncomfortable for him with the LO growing inside. He can't seem to move past it mentally, and so his efforts ended in frustration. I tried everything I could to be supportive, I even got creative with new lingerie. It ended in one sided rejection, with me feeling lowly unattractive. Talking leads to nothing but circles. He has stopped initiating completely, and all of my attempts are immediately shot down. He says it's to protect me from feeling rejected. He feels that if he gives a little, having to tell me no later will do worse damage. But no intimacy attempts at all just makes the insecurity worse.
We've never had a problem physically, even when miscarried last yr. But now we are just over 27wks in and my 5'6" former athletic frame is 162lbs. I trust him completely, but I am also realistic. Not being intimate with me does not mean he's lost his sex drive. Which means he's left to his own devices. We always been able to talk freely about porn. This is just the first time I feel like I no longer fit the description of "Hot" or "Sexy", categories which are undoubtedly full filling his needs currently.
Exercise, planning for the baby, balancing work and home.....Keeping busy only does so much for the brain. It makes me restless at night.

Has anyone else had experience with this?
Re: Emotions and Sex (tmi)
I figure I have two choices. I can take it personally or try to be understanding. It's a passing phase and as long as it doesn't continue after the baby is here, then we are good.
I'm sorry you're feeling insecure. Try not to put too much pressure on yourself and just give him the benefit of the doubt, that it's not you.
I try to do the same for him, even though I want to enjoy our solo time as much as possible while we still have it.
None of this is permanent and I would try not to take it personally. This is a big adjustment for both of you!
Just chiming in to let you know that you're not alone, at all. I could have written your post, and was wondering if I was the only one. I just remember that this too shall pass and do the best I can. We've made more of an effort in the last couple weeks to just spend time being as intimate as it works out that we can, even if we never quite make it to fully doing the deed, and that's actually helped my body image, us feeling closer, husband being happier, etc. At this rate, I slightly wonder if it'll be like October before we "do the deed" like we used to have no problem doing. The mechanics of this whole sex-while-pregnant thing seem to be just hard, frankly.
I hope this helps, if nothing else for you to know that you're clearly not alone!!
I might also throw it out there to him that you feel a little insecure and need him to reassure you that you're still sexy. Because honestly, I'm sure he still thinks you're hot. Men can be idiots and forget that we need to be reminded sometimes.
My hubby doesn't seem to find it weird to have sex with LO because "baby won't remember, and has no idea what we are doing," but I agree it is getting harder and harder to be intimate. With us, it is mostly my libido is a lot higher than his normally. With extra hormones upping emotions, it gets frustrating to get shot down. Not to mention, I feel unsexy because I have been having random periods of slight nipple leakage, and get really weirded out about it. He loves to play with my boobs, but when I think about them being crusty or leaking, it is a major turn-of. Goes with the PP feelings of being unattractive.
One thing we have found helps get us started is me giving him a blowjob. Your mouth is nowhere near LO, and could get him stimulated enough to try vaginal penetration when emotions run high.
I have heard other moms suggest these: Maybe reciprocal oral sex (if you can both get into it)? Or mutual masturbation (with or without toys)? Both options involve him not putting his penis near LO, if that is what makes him uncomfortable, but still helps relieve those needs.
I also agree with PP - maybe focusing on other ways to be intimate might lead to more sex...(??? definitely not a sexpert, here).
