Oh, this is an interesting topic!
At my HW, I encountered a few VERY attractive chubby chasers. One of them looked like a younger version of Gary Dourdan (Warrick from CSI...

) and said, "I KNOW you have a GORGEOUS, JUICY fat *** under those baggy pants." He kept telling me all about how he thought I was so hot and loved my "natural, healthy, curvy figure." I personally think I have a natural, healthy, curvy figure NOW - back then, I was just FAT
The other chubby chaser was a total metrosexual prettyboy type. I was pretty surprised to see that someone so hot and obviously vain was hitting on me

. I live in a shallow college town where a lot of guys are obsessed with appearances and seem to only like thin/skinny girls. We got into a conversation once and he said (like Shy Moment's son, who also thought I was sexy at my HW

), "I don't like girls with no meat on their bones. They look like they're going to tip over. I don't know why you want to lose weight; you look SO good the way you are. I
love plus sized women and honestly, I don't think you'd be as pretty if you lost more weight."
Any time I actually bothered to make myself look good at my HW (I was frumpy for the majority of the time) and a guy hit on me, I'd think, "Wow, you're either a chubby chaser or you have no standards."
But seriously, a lot of guys don't care as much about our weight as we think they do. Many don't even pay close attention to it unless you point it out.
As for what I like?
I'm bisexual and I have different standards for each gender. I'm not too particular on a woman's size, as long as she is proportionate and has a pretty face. A little overweight is fine, as is a little under. I don't like emaciated and I don't like morbidly obese, but anything in the middle is great.
Men, on the other hand, usually can't pull off carrying extra weight because it all goes into the gut. There have been a few mildly overweight men who I've found attractive, but I mostly like a medium frame with some muscle tone. My preferences are the same now as they've always been regardless of my weight and I've always had this little rule of "I can't be with a guy who weighs less than I do" though that was obviously a bit different at 175 than it is at 125...
OH OH... and yes, DO show off your legs!
