talk dirty to me *sax solo*

Does anybody here like dirty talk and/or are you good at it? My bf is really good at it (especially when he puts on that Irish accent, i die), but I'm AWFUL. I get so embarrassed. One time I was so flustered I froze up and needed like ten minutes to calm down. The best I can do is go along with whatever he says ('please I really want you to do x' or 'yes I am y' and the like). If he tells me to say something sexy literally I just do this weird giggle moan...thing. Lucky for me he thinks my embarrassment is cute, but agh!
