Let's see... Just off the top of my head...
my dress
my exercise
my diet
what i listen to
what type of writing i do
my schedule
my volunteer work
my career
my hairstyle
my make up
all of those are controlled, in some aspect, by my relationship with Master. Think that pretty well covers my life (for the most part) and hence the "life style" that i CHOOSE. Most of the items aren't sexual, although the TYPE of sex i participate in is part of the life choice i make...
Everyone has a lifestyle... a choice they make in how they live their life... it just doesn't have the sex with the "extras." (Too bad for them! *grinz*)
