Well, it's hard to say what a true sugar dating site is anymore.
There are a lot of sites and they all cater to different audiences.
There's traditional sugar dating, but also modern sugar dating, which I think is hand in hand with escorting. There is also just random girls who will let you buy them dinner and gifts and then never sleep with you. Is that what you want or do you learn towards the girlfriendly experience? (Meaning sex)
I have a list of some sites I've used or heard of and give you my impressions.
1.
Secret Benefits - Seems like the most popular site for luxury stuff, rich guys seeking attractive women, that sort of thing. Has more strict member verification, safety features, and a global community.
2.
SugarDaddy.com- Underrated sugar dating site. Women aren't interested in most men, UNLESS they sense you have big bucks and there are very lovely women here. The site is very discreet with anonymity tools and a very professional and sophisticated look.
3. Adult Friend Finder - Not really the point of this site but there are definitely sugar babies lurking on here looking for Daddy Warbucks.
4. Sugarbook - Pretty popular and reputable site with NSAs, discreet meetings, and live events which is cool.
5. SugarMeet - A bit more shady than Sugar Book, but still promises the same sugar benefits.
6. Ashley Madison - Similar to SugarDaddy.com, but more focused on married dating, and cheating. But yes there are definitely sugar babies here looking for Daddy Warbucks.
7. Elite Singles - Very much an executive level dating site, where rich people or working execs can meet up and talk about stuff other than work.
8. Luxury Date - Very simply site, not much known about it. Nice looking though, or that could just be the models.
9. Elite Meets Beauty - Pretty successful site with a growing population and an 85% college education demographic.
10. Established Men/Millionaire Match: Pretty fancy site with options like Certified Millionaire Status. Seems to be more serious than the average site.
11. Seeking - Another sugar daddy site, but supposedly quite a few scammer guys too. Private and anonymous, fairly well known.
12. WhatsMyPrice - Kind of the Walmart version of Seeking. Women just go on there to get bid on, get paid from it, and taken out to a nice dinner. Work likes a charity auction. Don't expect sex right away, but worth trying.
Hope this helps and I will add others as I discover them.
