Hi I'm 19 here I'm newly introduced to technology I got my new phone. I'm new here, this is my first time to post a reddit but weird thing happen is my friend ask me random thoughts that something I didn't know or heard about, he said "do you watch porn?" I replied to him "What is porn?" and he start bursting in laughter, However he bring his friends and ask "This guy has never heard the word porn", they started to ridicule me even called me a weirdo. I was really confused what is going on. Should I unfriend them and let go?
