I'm a Bicurious guy, but apprehensive about seeking out contact.

So, I'm sort of romantically involved with a girl now. We aren't dating now, but I see it down the road. Anyhow, I am pretty bicurious but haven't really told many people. I'm at a relatively small college now, but I'm sort of looking to explore this idea. I downloaded tinder, but the first prospective match was someone in my class. I'm kind of nervous about 'coming out' especially indirectly, I guess.Have any of you felt a similar way? Is there a more discrete way to entertain this idea? Thanks!
