The two main ways to attract people on this site is by posts and your media. I can understand discretion if you don't want your location and stats public but if you don't care then enhancing your profile would be key.
So 1. Make good, sexy, flirtatious, intelligent posts that will make them interested. 2. Give them some media that will make them desire you. 3. Tell them a little about yourself and what you are looking for in the lifestyle in your profile in the "about" section.
Lastly diversify and utilize a network of resources and you will have more success than you can handle. B2W is not necessarily a swinger site though it seems to have tons of swingers on here. So I would suggest signing up to a couple of swinger sites as well like: adultfriendfinder.com, sls.com to name a few. Once you sign up an actual pay for full access to the site again you will need to create an attractive profile and draw them in.
Hope that helps bro!
