For us it all depends on the situation.
If we are inviting a guy to the house we are highly selective because we live in a small community and don't need the drama of some guy showing up at a bad time like a family gathering. The guys that come to our house now typically either do a drive-by to see if we have company or text her to say they are stopping by and get the OK to do so.
If we are out of town she is more open to whoever wants to come by within reason. Size reigns supreme then. The only "restriction" is if a guy responds with a pic of a big cock she asks then to send another one with a piece of paper beside it with her name on it because a lot of guys will send a pic off an 8 inch cock and show up with 5 inches. She doesn't filter based on if they are married, have kids, etc...that is on them.
