I like profiles where the escort uses his actual pictures, rather than someone else's. There are ways of searching photos online and finding the source and inquiring into whether the source is actually the one in the profile. While it would be idea if the escort would have a picture with his face shown or would be willing to exchange photos, I understand the need for privacy and I respect escorts' desire to be discreet by not posting facepics. I think that they should at least be willing to do a non-recorded 3-second video chat. If an escort doesn't do face pics, then I ask for a body pic (no face) with three fingers raised to authenticate the pics in the profile. If they refuse, I'll assume their pictures are fake.
As for descriptions, I don't think it's about length or detail so long as it sounds like a serious profile. I don't like profiles that go like "hoTT escort here 2 satisfy ur desires !! TXT NAO!!!!" I know Rentmen has restrictions about content, but I like to know if there is something standard (kissing. BJ...etc) that the escort doesn't do.
