I want to throw my two cents in here.

A person can be entirely straight and still have an overwhelming desire for maternal touch/soothing/comfort. I have this deep need, due to emotional and physical deprivation of it in childhood. Yet I am definitely not gay.

In some cases, if a person is gay, I can see how a desire for comfort from a t "could" become se*ualized. But it may not either. And a straight person can badly want mothering nurture too.
