As a general rule no.
While there has been the occasional examples of people having their sexuality un-commanded change, its not common.
Its sure not possible to choose to change.
I can assure you if you had a pill that would change me from gay to straight I would drop it in the bin. I would because I have been around long enough to know that being straight is not the path to life's happiness.
The answer to that is being content with what you have in life and being thankful for it.

No more than a person could convert from straight to gay.

Some can change their behavior - but not natural preference.

No.
I suspect Milo is going through an identity crisis.

No. Same answer as the last 10,000 times this question's been asked.
You can't change from straight to gay or bi, or from bi to gay or straight, or from gay to straight or bi. None of the above. Can't be done.
Milo probably dresses in plaid shirts and overalls because of where he lives and how he spends his time (if he has any sense). I dress like that and I'm queer as a three-dollar bill. Clothing has nothing to do with sexuality, and sexuality can't be changed (except perhaps by a traumatic brain injury...maybe).
So, relax. Nobody has ever changed, and nobody's ever going to make you change. And there SHOULD BE no reason for anyone to ever WANT to change.
