See I definitly think that your prefrences can be influenced. I don't dissagree with it being pre-ordained with your genes, but there are quite a few undecided individuals out there waiting to be influenced.

The point of my two questions was based on exposure to one envoirment for a number of years prior to learning about the other prefrence. I would assume that most children learn of marriage from observing there mommy & daddy from the point they learn to do everthing. There is probbibly a span of well over 10 years before that individual is introduced to and understands homosexuality.

Reverse the scales, does that child turn out the same being subjected to mommy & mommy or daddy & daddy day after day.

Also your genetic point is well taken. How many individual are influenced to think they are straight because of the enviorment that they are raised in only to be confused and learn at a later in life what there true sexual prefrence is.
