hints from my gf

my gf has been saying comments here and there and im wondering if she really means them although she says them in a joking way like..."you know I like em big" and things to that nature. We play with dildos after we have sex and i have an inflatable plug and a 8x2in vibrator that she enjoys. also the other day in bed when we woke up I was extremly hard and leaned over and my erection poked the side of her leg and she said something like "down little boy or oouch thats a hark little penis you got there" what do yall think?
