I was thinking I would use it for my regulars, gents that I would have some trust placed in.
But yes, the app is free. You can't just view things like a profile, two people have to have usernames and approve "friendship", then you can send stuff. One of my weirdo friends sent me a video of him getting outta the shower and whipping his dick back and forth to smack on his thighs...
He's not from the hobby, just a funny guy but it always catches me off guard when he does it. But you can set the time from a second to I want to say like 30 seconds to view and now you can do multiple videos back to back. It's pretty neat.
