Boyfriend disinterested in sex... do I break it off?

Terra

Ladies, I need your advice. I’ve been dating a guy for a year now, he’s kind, smart, very attractive, he listens to me, I know he cares about me and I am 100% crazy about him. I am also 100% going crazy over his lack of interest in me sexually. Don’t get me wrong he politely participates 80% of the time. But when I kiss him or try to initiate it always seems like he’s trying to politely shut it down, he’ll quickly kiss me and then make a point of turning his attention to something else. We do typically have sex twice a week but it feels like he’s giving in to hit a quota and it’s completely passionless on his part. We’ve talked about it and he assures me he’s attracted to me and likes have sex and doesn’t feel like his drive is diminished but nothing seems to change. I’ve never considered walking away from someone I love but it’s really starting to mess with my self esteem and I worry the deeper I get the more I’m setting myself up for a lifetime of feeling unsexy, unloved and lonely.
