I have (before the damn FOSTA law). We had visited via Kik for a long time, then talked on the phone several times. I knew his personal information and looked him up on several sites including the state that he lives in "case net" (any legal actions), and found him to be who he seemed to be. Nice guy, professional, etc. He even flew quite a distance, and I even stayed at the same hotel in a separate room. We had a wonderful time. He is still a good friend, however, spending a couple days with him, I realized some personality flaws that I would consider quite disheartening if I were to seek a IRL relationship with him. First, he made it his mission to meet cam models or those in the industry. He is obsessed with sex workers and traveled world wide to meet them! He also had a cache of pictures and videos from almost all of them. He couldn't wait to share some of them with me, showing me "Lisa Deep Throat" or "Debbie Dildo" pictures that he had taken, and tell me how much he enjoyed this or that about each of them. It hit me that he'd be doing the same thing with another woman and share MY pictures, etc.
I am still in touch with him, on occasion. He wants to fly out and visit again but I am just not that excited about it. I didn't have romantic feelings about him, truthfully, because I am old enough ("mature") to know that meeting a client usually doesn't end well, either because of disappointment, or because he/she is a wackadoodle.
Best of luck and please be safe. Be sure to vet the guy through as many resources online as you can. Even if you live in the same town, get a hotel room. Have your own escape place in case the guy is not what you expect. Be sure to tell a friend, too. I had a girlfriend call me both days I was with him just to "check in". I told him that, too. Who wouldn't do something like that nowadays? He was perfectly fine with it and even said it was a good idea. Let him know you take precautions. Trust your gut and be safe. Let us know how it goes & if the person you believe him to be is truly who he is.
