So I will likely get down votes as my opinion is not really PC(apologies to you single women who do not fit what I see as the majority of JW woman), however as a self supporting, financially secure man who has been single for a number of years I have noticed that JW females of a reasonable marrying age fall into two main categories. Those who are married and out of the dating "pool", and those who are single for very good reasons. They are more so than any other group of people either mentally unstable and heavily medicated, have ill behaved children, the woman is just looking for a meal ticket, or they are physically unhealthy (obese, chronically ill etc.)
As a man who is very active, enjoys the outdoors, has a tidy nest egg built up and am self employed I am not interested in the JW pity marriages that are seemingly required by most members. I enjoy the recreational and intimate company of healthy, active, fit women who are not JW drones, and are also financially secure. So as far as "dating" sites I would stay clear of them too.
Get out and about, go where the type of woman you wish to spend time with is, and to hell with the JW busy bodies who will always find an excuse to gossip about you and try to guilt you into acting like they demand. And any elders who try to rule you with FOG, tell them to FO.
