Me and my friend might have something?

I have a girlfriend and so does he. But when ever we sleepover. I want to have with him. And I think he is to because he gets close to me whenever were just sitting around. Or it could just be him joking around. Which he does a lot. And one time him and I took a shower together. WITH SWIMMING TRUNKS on. But I could tell he was turned on by something in the shower. And I thought it was me so I got turned on and I felt his " By accident" and he said wow dood! Little personal. Then he laughed and winked at me. And I think me and him could have something. Plus me and him joke snuggle together when were in bed. But I think he likes it. I really think he is biual and I think I might be to. But I really feel weird around him now. Were both 14
