I'm not really sure what to do.

If you really want to help me out, please read until the end.I'm a teenager, using my throwaway since most people close in my life know my main account, and recently I had a small awakening, almost.Now keep in mind that I grew up in a very conservative family, and myself am very conservative. Up until about a year ago I was rather vocal about being against LGBT culture and the ideas that came with it, when lately I've learned to just stop caring and let people be ok with what turns them on.I, up until recently, was very adamant about being straight, but something happened. I was looking through a few porn subreddits, when I came across a solo image of this dude just holding out his massive dick. Normally I would be disgusted and carry on, but something about it made me stare. I got more turned on by that than I have any other woman, and I just couldn't help it.Does this automatically make me gay or bi, something along those lines? The idea of stroking someone else's cock or even sucking on it really turns me on, but I just don't think I could go all the way with it. I'm just really lost at the moment. I can't exactly talk to my parents about it as they still are adamant against it, and I'm not fully sure they'd be ok with the idea of their son being interested in other guys.
