looking for adult opinions please

i'm talking to this guy that lives in indiana. i live in louisiana. he's planning on coming to new orleans in october and i live 45 minutes away from there. he's driving here for a concert there and we talked about him driving to where i live and  staying in the hotel that's right next to my house for the night or day. hes 19 and im 14. he brought up doing "adult" things. i asked on this app because there are plenty of mothers, adults, experienced girls, girls that went through this, and older sisters that know better. i'm an only child and i am definitely not talking to my mom about this. i want to do it but i just feel like i need opinions from actual people and people that actually know.
