Best way to "explore?"

Quick summary: I'm an 18 year old bicurious male in the US who is bicurious and looking to have a brief and non-serious sexual relationship to see what I enjoy. However, I don't have any gay friends or acquaintances (and in fact, see/know almost none that I see regularly). I'm looking solely for a sexual experience, not a romantic one.I haven't had much any success with Grindr but, since I'm 18 and in the US, cannot go to bars. Any suggestions for other methods to look into that?NSFW tag just in case.
