need opinions

My sister-in-law sent me a message regarding my post on being attracted to men, and I think I need help understanding what shes saying. Here is the quote:

"Have you ever stopped to consider that not only was your first sexual relationship was with a guy, but your longest as well? I certainly remember you were very attracted to females young but that was theory, what your physical experience was with a male. Sometimes based on how often you talk and think about those days, I wonder if you ever left that relationship or if it just became something different inside you."

opinions?
