I strongly suspect it will be a scam. All the profiles will be fake and “flirts” sent to you (and I promise you'll get them within minutes) will be from bots to entice you to upgrade to or maintain a premium membership.
Based on your profile @dr65952 , you'd be looking to hook up with a female enemate, right? Hover up for a minute, look at it from the woman's point of view, and ask yourself why in the world a real woman who is actually looking for an enemate would have to pay a subscription to find one?
My guess is the majority of true klismophiles find their way to either zity or fetlife (or both) at some point, right? Ask any woman here or on fetlife who has given any indication whatsoever that she might be open to a new male play partner (much less placed a personal ad) how quickly her e-mail box fills up. Many leave because of the myriad unsolicited friend requests and DM's.
I'm afraid you'll face a harsh reality - a very small percentage of the population is into enemas sexually, and a very small percentage of those people are women. It is TOUGH to find an enemate , so you have to be patient. If you made the women pay to hookup it would be even worse, wouldn't it?
I say all this with some unfortunate experience. My elderly father has been absolutely bilked by whatsflirt.com for many, many thousands of dollars over the last few years. He's a lonely, virtually penniless old man who desperately wants to believe that beautiful women 30 years his junior want him badly and can't wait to hook up with him for sex, and whatsflirt charges him something like 50 cents per outgoing message to respond to messages he recieves from bots linked to fake profiles. They'll engage and can't wait to meet him, but there is always a reason why it can't be until next week, and then when a firm date in the future is finally set something comes up and they have to postpone. That's the best case.
The worst case is the woman is a real person catfishing. In that case once he's hooked “she” needs money - “she” doesn't directly ask for it, but “she” lives far away and would love to come spend the weekend with him, but she just doesn't have the money right now :-(. Or her car broke down, and she couldn't get to work so she lost her job, and now rent is due, etc. :-(. So he'll send them money.
Yet I cannot get him to realize this consistent stream of expensive disappointments is anything other than a series of individual bad actors - because he doesn't want to believe it. Those types of sites infuriate me.
I wish you the best of luck, OP, sincerely. I do hope you find what you're looking for. But it won't be there.
