You do have morals and rules when it comes to sex: you've set yourself limits you won't go beyond when it comes to respect, mutual desire, communication, sharing fantasies and feelings. All this doesn't stop you from flirting with your limits from time to time, but you never actually cross the line. You like to flirt but you also need to know he feels the same way you do. The complicity you have with your partner allows you to explore things together and confide your deepest desires to each other.
Advice for you: Be careful not to play with fire just to reassure yourself about your sex appeal - you could get burnt. Make sure you respect the limits you set yourself.
