Phone Sex?

My boyfriend brought up the idea of phone sex the other night and i want to try it but i just don’t know how or what to do, we’ve talked dirty to each other over the phone before and we’ve done some stuff irl too i’m just not sure how it works i’m a very litteral person and if i don’t know what i’m doing i get nervous and stuck so if any of y’all have any tips or tricks i’d love to hear them
