i want him to talk more during sex

my boyfriend and i have a great sex life, the only complaints i have is i wish he would initiate sex more and i wish he was more vocal.  i want to hear him moan and i want him to talk to me more/dirty talk. how do i tell him these things without hurting his feelings or making him feel like hes not good enough?? i talk to him a lot during sex saying stuff like "yes that feels so good, i love your dick" i let him know when im gonna cum etc. i would melt to hear him say he loves my pussy or anything like that but how do i get him to say this? is this a conversation i should have with him prior to sex or while we're having sex should i just say something like "talk to me baby" or "tell me you love my pussy" or what?? please comment
