I was at my best friends house and she was showering I was is the tv room with her brother and his best friend which I both know really well. They are one grade higher then me and my best friend. So I walked in the tv room and her brothers best friend jumped on me and we where over each other on the floor and he kissed me. Since then I couldn't stop thinking about him but I don't think that I really like him cause I'm still kinda young but I kinda like him and I just need advice

pls help me
