To my knowledge circles don't force celibacy excluding mages-templars relationships for a good reasons.
They can roam as long it is in the circle. 
Bayonet suggestions resolved around pretty much turning circles into some kind of "entertainment house" that would compromise safety of rest of Thedas over comfort of the few even more, what isn't point of the circles.
Good they did that , security of rest of world should have priority here.
And yet the rest of Thedas is NOT secure. Certainly mages can present a threat, given the powers that they possess, but, there have been wars between the races, bigotry, despotism and genocide that have absolutely nothing to do with the mages at all.
I still question why the "Chantry" is the ultimate authority in this whole thing. It is just another religion. Admittedly the events leading up to it's founding were of a noble nature (although they obviously solved absolutely nothing since the Imperium apparently just continues on as it always has with minor changes), that does not give the "Religion" the ultimate authority of what is "best" for the entire populace.
I agree that the Templars can serve an important function as can the Seekers and the elders of the mages, particularly in the guidance of new and novices of all the factions, but the Chantry needs to be taken out of the equation. They ARE NOT the ultimate authority. Each culture has it's own way of handling the situation and, while I may not always agree with the methodology, the Dalish, the Qun and any number of other independent City States have found other ways of dealing with this situation which does not involve kowtowing to a particular religious order (I am not counting the Qun as a religion, more of a philosophy that organizes their particular society).
Perhaps my own biases towards the abuses that always accompany organized religion are showing, but...
