i feel like i should post on this thread, cause i've always had a fetish for curvier and bigger women but that doesn't mean i don't find thinner women attractive also. My recent ex was only about 100 pounds and I thought she was absolutely beautiful and sexy especially since she had some traits that I really liked, it's probably the same with your boyfriend. He probably loves you for you, but I'm sure he wouldn't mind if you put on a few haha
