Okay, like you and the other respondent, I feel like that too, MANY times. Amongst everything else, this is the last thing I think of!
BUT... be thankful your Hubby DID express himself to you. That is good. He must feel close to you, in order to do that.
For a man, the physical aspect of a relationship is very real...that is how they feel 'connected' to their partner and how they feel 'whole' and how they feel 'loved.' But its normal.
Sometimes, you just have to do it and make it fun. Smile, tell your Hubby you love him (they need reassurance too), and that you 'hear' him and understand. You do not have to make it a huge big deal or put on a whole show and charade about it. Just be yourself. It doesn't have to be some 2 hour moment....I think for a man, anything physical/sexual is fun for them. They just want to feel special and that they make their wife happy. For a man, this is what they equate with making their wife 'happy' too.
For me... sometimes my hubby is at his desk working or studying & busy as usual... the kids are napping, and I'll just say "hey, we're all alone!" (wink)... and then wow, it's exciting because it's the spur of the moment! Then after that... you just see how happy Hubby is, just like a child who won a prize or something. It's so simple, but yet so hard to do sometimes, and well... it's easy to just let it be neglected.
Like anything, it takes effort for some. I think for a lot of couples. They just don't go around advertising it. I give you credit for even asking this question, because it is so personal. Good for you!
Main thing, remember that men... get shy too and they are reticent to initiate anything as well, because they 'see' how their wife is so busy with the kids, and tired, and on and on and on. AND they don't want to be turned down and be told "I have a headache...." blah, blah, blah. But as my Hubby said, if a man and wife don't connect sometimes, they might as well just be room-mates, and 2 ships passing in the night. Then you lose touch with each other. I am actually glad that my Hubby expresses himself to me this way (like your Hubby), because it really shows me how much he cares about me, and loves me still after ALL these years of being together for 12 years. And he only wants me. It brings tears to my eyes. So, even though my libido is not as active as his.... I try and make this happen for him... and me, because it is so beneficial in so many ways, for both of us. And even if initiating it is hard in the beginning... I am always glad after wards. Because we just feel closer, again....amongst all the busy-ness.
All the best,
Susan
