Confused

I am 21 years old and a junior in college. I have considered myself straight my entire life, but over the past few months I have been having more and more sexual thoughts about other men (just in general, no specific person). Unfortunately, I’m not in a position where other people can find out I want to explore this (or that I actually did). How do I best go about trying to explore this side of my sexuality discreetly? I have no connections to the gay community in my area.
