Sound Bite - No frills adult & casual dating site with large membership. Good feedback.

NaughtyAdultDates.com is a fast-growing and exciting place for UK singles looking for some adult fun. The membership is really active (over 1.3 million), and you're sure to find exactly what you're looking for (if you know what we mean!).

The design is very basic, as is the functionality, but it has good reviews for doing exactly what it proposes to...putting people in touch with each other who are looking for no strings fun. There is a high percentage of men on this site, but with 1.3 million members there are still plenty of women to go around!

Oh, and it's totally free for women, which is great news for the men.

NaughtyAdultDates is powered by White Label Dating. Here is a bit about them:

WhiteLabelDating.com claims to be the UK’s leading online dating provider and is a subsidiary of Global Personals Limited, a UK-based software company that enables companies to set up their own branded, online dating sites.

White Label Dating powers a wide range of sites, from large publishers to smaller dating sites run by individuals, often provide for niche dating interests.

WhiteLabelDating.com’s services include the provision of the backend system requirements, software, billing and customer support, as well as database management.

The company is very good at what they do. They are constantly trying to improve the user experience, focusing mostly on Customer Services. They are currently the only company we've come across who go so far as to monitor the "first message" new members send out, which is a very effective way of reducing instances of scammers.
