Im not sure how I feel about this. Was what I did wrong?

My guy friend and I are good friends, he is 15 and im 14 we've been friends for 6 years, but we are just friends and that's all we will ever be. But we were spending time at the pool yesterday, and he ended up asking me if I would let him touch my . I said no that would never happen, but he talked to me about it and I said I would think about it. Then I saw hm at school today and he invited me over to his house. His brother was already home, and his parents only let me over because they think his bother is super responsible, when he really doesn't even care. So we just went up stares to watch a movie in his room. He asked me if I thought about what he said, I said I would let him do it as long as he would keep itt between us and I said it would never happen again. He agreed so I just took my shirt off, and he reached out and grabbed my s, then he took off my bra. He could tell I felt kinda shy so he took his clothes off and just stayed in his boxers. And stuff happened. We kinda ended up making out (he tried to take things further and I told him not to). But I didn't really think that would happen, I just thought hes curious and id just let him do it and that would be it yah know, just a friend thing. But we ended up making out. I don't know how I feel about it, I mean he is jake, hes just a cute dork that I met in elementary school. I don't think of jake in "that" way, but yet that happened. Was I wrong to make out with him even though it meant nothing to me?
