"So I get why people have to label it how can you be this close without it being sexual?"
Homosexuals have been asking that for years.
I think it stems from never having a close relationship with their parents, friends, siblings, God, neighbors, grandparents, teachers, mentors, etc. etc.
Sex does not equal love. Sex is not the ultimate expression of love.
Not at all. Just the exercise portion so that you insure a long life together. :) 17th anniversary was yesterday.
