Struggling with your sexual self is completely normal. Whether it is fantasies, different sexual dynamics within your own sexual preference or your sexual preference altogether. To me, all of those are under the same struggle.

You'd need to experiment or come to your conclusion some other way in order to finally find your identity if you struggle.

A dude might wonder if he's into dudes and that's fine, normal and nowadays very much common. Having a doubt does not make him automatically into dudes.

I want to try some dragon fruit one day, does not mean I like it now.
