It could be fear of men, lack of trust for adults or inability to enjoy normal sexual relationships.

Trust is the fruit of a relationship in which you know you are loved.

I have no fear that the result of our experiment will be that men may be trusted to govern themselves without a master.

He feared me as many men fear women: because their mistresses (or their wives) understand them. They are scarcely adult, some men: they wish women to understand them, and to that end they tell them all their secrets; and then, when they are properly understood, they hate their women for understanding them.

Of all the wonders that I yet have heard,
It seems to me most strange that men should fear;
Seeing that death, a necessary end,
Will come when it will come.

They're going to be the salvation of this process.
