Being less submissive during Sex?

Emily

My boyfriend has always asked me to be less submissive/more talkative during sex. Any ideas on how to accomplish this in baby steps? A lot of it is that I’m not super experienced and shy but I want to start doing small things. I do get on top and all I think he just wants me to initiate more and talk more- I just don’t know how to initiate I always feel silly talking too much? Any advice on what to do or say would be appreciated!!!!!
