Well as someone who falls into the BBW category....it would depend on how the site is geared.
Before I met my current sweetie, one of my friends and her SO tried to set me up with this guy he worked with. (not a swing situation) We weren't hitting it off greatly or anything, but figured I would be ok meeting up with him again for a lunch or dinner date so we could actually chat and get to know each other a little better (the original meeting was basicaly a 'double date' with my friends and we went to a pool hall, which is ok...but felt a little too high pressure for me to give a positive response if that makes sense).
Then he spoke the words that drove the nails in the casket. He was standing behind me and sort of running his hands down my sides to my hips and back up and says something like, 'I love girls like you that have some meat on their bones...' or some similar sounding tripe. Yeah, totally shut me down. Not that I'm ashamed to be someone's 'type'...but if you can't see past my size, hair color, boob size, etc...then you aren't seeing ME, you are just fixating on something about me and that is a total turn off to me.
So guess who didn't get his calls returned? lol
Personally, I will stick to the all inclusive type sites. Partly because I don't want to be singled out as a 'type'. Now, do I feel more comfortable being naked in the same room with a female that is of a similar build? Sure on some level. Would I want to be stood next to Pepper or Tybee or Mrs. Spoo (who are all totally smokin' hot )? Possibly not. lol But would I want to exclude myself from being potentially contacted by them by not even listing on AFF or SLS (or whatever 'all's welcome' type of site)? Nope. We've met and played with some great folks (HWP and some that weren't).
