I don't know. does he want to experiment?

When you see him, go to a place where no one can hear you. Tell him that you love him, for real. It's no use keeping things in the dark. If you really, really love him, let him know. Make sure he knows that it's not a joke. Have a serious talk first, and if he's ok with it, ask him to experiment. I'm lesbian, and when I talk to a girl I like, and no one else is around, I kind of smile and joke, but not obviously. Just enough so that they get the message. If he says yes, go for it. And remember, if he says no- puppy dog eyes do NOT work. Just tell him that you really thought you had something, and walk out with dignity.
