Do some boys really like a little meat on girls bones?

im subconscious about my weight which i recently gained, and my new boyfriend (who started dating me after i gained the weight) and i were talking about it and he was saying he doesnt like skinny girls. he likes a little meat on girls bones, aka me. and yeah being anorexic isnt pretty, but his ex has a great body, athletic and stuff. and i feel like he would like that but he says she was too skinny. so basically are there guys out there that like a little junk in the trunk for real?
