Actually being a regular and having it turn in to something more,usually just a friend in my experience,that can be hard on the guys sole too.
The human factor will allways play apart when seeing an SP weather it's once or more . Some girl are more intuitive and pick up on who the guy is . His pain , is love and his caring and like wise we see it in the girls we meet .That will do something to a person and either draw you closer or make you run.
Maybe sex is fun and we all need some infancy and another person to hold and confide in . Many of us find it with the escorts we want to see.
The sole is often layed bare with each other .and it can be hard and suck the life out of you ..just like any relationship on mutable levels.
That girls run into more of the needing ,clinning and controlling people is part of why guys pay to see girls . It does take a lot of strength to handle and it burns girls out .
Of course everyone is looking and hoping for something more then just this.
