I like to take what is usually a fairly mundane need and turn it into something great.  Whether it is myself that I tease, or something else.  Orgasm is almost an art form.  Though I like the idea, I don't really have much interest in denying someone for a really long time because the urges lessen.  I like that state of desperation, but not so much the begging.  To me chastity is more of a gift, freely given from one to the other for the purpose of mutual pleasure.
