Actually, Fetlife is still the best bet for you. I happen to have been on there since about a year after it started, and I currently "own" a number of groups, where some of your answers can be found.
Two of those are Classified Advertising groups, sort of a Brother Sister pair of groups, where they are complimentary, one for
Dom males only and one for
female subs only.
I started assisting, the founding owner of those pair of groups, as a moderator, many years ago, and some years later, when he died, I ended up being asked by his widow to take over the ownership of the groups.
The total membership in that pair of groups is now over 20,000, actually, I just checked and the total for the pair is now 20.293.
(6,021 males, and 14,272 females)
There are a lot of very strict rules in those two groups, and I am on there very often, daily at least, sometimes more per day.
Location has to be shown at the beginning of the ads, and other things, such as NO *censored* pictures. Many other thing are also helping make these two groups very popular, such as no flaming, harassment, putting people down, and the women are very highly protected in these two groups. As a result the ration of women to men advertising in my groups reflects the popularity with the women.
If you go to my personal profile on Fetlife, and look down the left side, you will see I also own a number of other Classified Ads Groups, some of which are open to other outlooks, other than limited to just pure dom men seeking sub women. But I do not "work/supervise" those as much.
Here are the names and links for the two most popular of my Classified Ads Groups.

Classified! Male Dom Types Seeking female sub Types

This last one above, is THE ONE you want to run YOUR ad in.
DO NOT put your male ad in the women's group, because you will get DELETED and BANNED from all my groups.
READ THE RULES carefully, before you post your ad.
These rules are WHY these groups are soo popular with women who join and run their ads in my groups.

(This profile is still open, and refers people to the newer one, so people can find me by the name I am most widely known as, "Master Seth"
More people in this world know me as Master Seth, than my real name which is Robert Ernest Wadlow, same name as the tallest man on record, my 6th cousin, who died in the 1940's, Robert Pershing Wadlow.
I also have a personal website, (http://master-seth.com/HomePage.html). On the Home page, you can find all my contact information, phone for texting, email address, etc.
Most of it is not kept up to date, but the Educational Page (http://master-seth.com/TheGSpotandMore.html) is pretty up to date. It is the required reading for my students on my teaching of Female Anatomy.
Good luck in your search.
