I've tried a few sugar dating sites. This one has by far has delivered the best results with actual successful dates. They also have the best design, support, and don't charge a monthly fee. Don't just take my word for it. It looks like Secret Benefits has excellent reviews across the web. I fully recommend checking this dating site out.
