Confused please help need reassurance?

Basically I had a great life enjoyed everything etc come from a wealthy family etc... Then possibly 2 months ago I began to just feel different from the way I'd normally feel on a day to day basis... Progressively I began to feel sexually confused and couldn't understand why as there was no trigger... I.e crush as I have and still am very attracted to woman. I began to get these intrusive homo thoughts that people have no control over. All I want is to get back to the way I was b4 living a happy life as a straight teenager I really don't want to be homosexual I have nothing against them I just want a wife and kids and a family... I plan to have sex with a girl tomorrow and we have discussed it so hopefully that will be good. That is irrelevant but all I want is some reassurance... Is it normal for teenagers to become sexually confused for no reason? Regards but only positive answers please thank you x
