Is my friend gay?!?

So I have a friend who I suspect (hope) is gay or bi. So let me tell you some of the details. We go to the same secondary school. We're Both aged 17. We became friends about 5 years ago in the first year of the school but it wasn't until really 2 years ago we became close. For the past year we've been snapchating each other all the time.A few moths ago while another friends parents were out of town our group of friends came over to stay the night. While we were watching a movie I sort of cuddled up to him while we had a blanket over us on the couch, didn't faze him at all.Then two months ago they all came over to stay at my house. Conveniently come night time with the lack of beds he had to sleep in my bed and the 4 other friends stayed in an other room. Because we're that sort of bro-type group of friends we slept head to toe because it would be "gay" to do other wise. But it didn't take me long to find an excuse and I started rubbing his leg while we talked. I then slowly creeped my hand up his thigh and around to his butt. Again seemed pretty comfortable with it. That night I cuddled into his legs.The most recent thing to happen was only three weeks ago. Again a group of friends were over at my house staying the night. Because there was even less beds, to make things "easy" I said to him will you sleep in my bed and of course he was quite happy. Like last time we slept head to toe at first again cause we're just "bro's". But while we were talking he wanted to show me a video so I thought it was best if I came down his end of the bed. While wathcing these videos I played with his hair twirling it, running my hands through it, etc. An hour passed by watching YouTube and he rolled over to go to sleep. I started to spoon him which he was fine with. We fell asleep for a while but later on I woke up so I cuddled into him a bit more and then put my arm under his t-shirt on his chest ( I was the big spoon). I was worried when he woke up he would feel uncomfortable with our spooning and my arm but I was committed plus I didn't want to move I was loving it too much. When we eventually woke up I stayed the way I was, where my hand was positioned by accident on his nipple. We joked about it and I started playing with it, we were shocked at how it wouldn't get hard.Some more details, I can't tell if he was conscious of it but while we were spooning my hand wiggled its way down to his junk where I got a quick feel. He sort of moaned when I did it.The thing is though he texts these random girls he meets on this app connected to snapchat called yellow and is always going on about the girls our age. I believe like most closeted people he just does this so people don't get suspicious especially since we go to an all boys school.Tell me your thoughts, I'm ok with him being straight. It's just the sooner I know the sooner I can find someone who I have a chance with.
