If his parents are already supporting him for a six year medical degree, then why is he so worried about coming out as a bisexual in front of them? It's obvious that they want to support him, I wouldn't see being bisexual as such a big problem to them.
Unless his parents were un-accepting homophobes to the extent that they would disown him (e.g. members of Westboro Baptist church), in which case I think he would be better off without their support. But I can't imagine that this is the case
