<human>: Can you condense the text into three sentences or less?

My boyfriend has a thing for chubby redheads with glasses and freckles. Unfortunately, that isn't me. I'm thin with dark hair, 20/20 vision, and only a faint dusting of freckles in the summer.

When we have sex he always gets me to push my stomach out so that I look chubby. I don't mind doing this, and it's hot to see how much he enjoys it, but it ends up feeling like he's just getting off to an ideal he has in his head. I'm not sure if he's attracted to me in my normal state.

I've seen him comment on how he finds "super thin" bodies and visible ribcages repulsive, but when I recently gained 10lbs he said "you're not super thin anymore". So I guess he thought my body was repulsive before? :/ I still have quite a prominent ribcage and I think it's a turnoff for him. He's dropped a lot of hints that he wants me to gain weight, but I have eating issues and it's honestly one of my biggest fears.

I think I'd be a lot more comfortable with these "preferences" if he didn't tell people about them...but he does, and I find it embarrassing. I'm scared they're wondering "well, what's he doing with *her*, then?". 

He reassures me that he loves me and that he's attracted to me because of the connection that we have, but I can't help but feel that I'm not enough for him. I feel sick just thinking about this. Any advice?
<bot>: BF likes chubby redheads with glasses and freckles. I'm none of those things and I'm super insecure about it.
