JayMatt,
Speculating, it seems to me that perhaps it is worse when a girl goes off compared to a guy. To use one example, if both a guy and a girl go off in the worst way, hamavin yovin, the girl is more permanently affected (not at all to discount how a guy is affected) to the extent it changes her future kesuba. I think it may play out similarly perhaps with other issues as well.
This is just a personal thought; not certain as to its accuracy. Any thoughts?
