I think I'm in love

So recently I've been talking to this one guy. He's so cute and sweet. I fell in love with him after talking to him for just a little bit. I know I haven't really known him for that long but as soon as we started talking I just fell in love. I don't really know how to tell him without sounding weird or creepy. But I feel like he's the perfect guy for me. BTW he's gay and so am I. Could I be provided with some advice. Like what I should say to him or if I should say anything at all.
