Im 17 and have not even had my first kiss but have changed a lot recently and have ben more confident. It is pretty easy for me to talk to most people latley. And i started talking last week to this cute girl that sits next to me and was doing ok and making decent conversation. But I started liking her and this week and when i try to talk to her her words get stuck in my throat,my heart heart pumps faster, and when i try to complement her my face starts turning red and the words cant get out. What do i do?
