I am starting to feel very sad... Everyone mentions it about me. Please help?

So I dont have not the most manly voice. And theirs at least one person every day who mentions something about me being gay. Today a friends friend mentioned me looking like a transvestite. My dad is a straight forward guy and he said all his friends who are girls mention and handsome and cute I am, so that makes me feel good but this is the straw that broke the camels back. For the record I believe that all men and women are to like the opposite sex not the same sex. I have republican values. When i get of age I am planning to get surgery for my voice. Please help. Hw much would the surgery cost, a surgery to deepen my voice. What would they do? What would be the side effects?
