He doesn't want to have sex with me.

I don't understand. Im turned down WAY more often than he is. We have sex less than once a week and that's us TRYING to get pregnant. Every time sucks because it's been too long for him and it lasts for hardly two minutes. I can walk around in nothing but underwear and he doesn't even look up from clash of clans. I try to lead him to the bedroom and it's "babe. Im trying to finish this show." Or "this clan war ends in 27 minutes." It makes me feel so freaking unattractive and undesirable. I'm not an ugly person and I'm in good shape. Nobody else seems to have this problem. When we're not trying we have sex maybe once a month and it's not that great so I'm not really interested in doing it more. I don't need him jumping my bones but a little interest or feeling noticed would be nice.
