In other news... Hubby and I suck. Our sex life is nonexistent. I just can't get excited about it. I mean, I can get excited because my vagina is ridiculous and always ready but my mind isn't into his body so I'm always eyes closed or mind wandering which isn't cool so we just don't do it.
I am sorry that this is so distressing to you

. From my perspective (an internet stranger who only has the vaguest idea of your situation) it sounds, here, as though you have an expectation of what sex
should be like with your hubs based on what you know that it
could be like. And that if it isn't that - eyes open, fully engaged - then it is not worth having?
In my mind, there is nothing inherently wrong with keeping your eyes closed and focusing on sensations while your mind wanders to other fantasies (or your shopping list

). To take it out of the sexual context - I love my Mom, she invites us to Thanksgiving dinner, and we attend every year. Do I love her cooking? (No!

). Do I love spending time with extended family that I have nothing in common with? (No!

) So I enjoy participating in a ritual that is important to her and helps strengthen familial bonds? (Yup - mostly,

)
It's frustrating and just... so disheartening. I love him so much. Why am I not really attracted to him ?!
This is an excellent question for introspection (and a good therapist!). I love my husband to pieces - but have to acknowledge that my attraction for him is more emotional and intellectual than physical. (I have my own theories for this for us based on our history...yours will be different.)
... he is frustrated because I am not an enthusiastic instigator with him. I will willingly offer and agree to sex, but I don't crave it with him.
To me, again as an outsider, this seems to me to be very close to a highly agreeable compromise - you can't change your cravings but your behaviors (offering up and participating willingly in sex) you can make a conscious decision about - if that is not acceptable to him, then that is something that he needs to work out.
Probably wouldn't bother him as much if it was all around an issue instead of clearly being just with him.
I do mean this kindly...but is this a case of TMI? Your relationship with him is your relationship
with him - why does the sexual attraction that you have for others have to come into the equation at all? Each relationship has its own dynamic - and it doesn't have to be the "same." Personally, I feel that one of the best arguments for poly is that one partner
can't be "all the things" for another person. I have different friends for different activities and conversations. I have different partners for different forms of intimacy.
