I have had a few, some from escorts who have asked beforehand if it was OK to send them, some from escorts who didn’t even enquire if I used a separate phone or even if I was the only user of the phone.
Personally I have no problem with such texts, but I can see situations where it could be a problem.
I think, as in all things, the magic word is consent. Need to be sure "green light" has been explicitly given, not just assumed.
I have had one text ever but have got a few pms from girls to say that they are back in my area on such a date.
I'm even more confused...she rang me...
