DATYs can be like coming attractions, you know those Movie Trailers we see in the movie theatres. A good one just makes one want to really go see the movie (ie wants my dick inside of her) and vice verse a bad movie trailer...well you know the answer.
Sometimes I know I cannot really physically perform because of too much drinking, stress whenever I visit a massage place/sauna; I would let the masseuse know so she doesn't think it is her fault. I feel so bad watching some of these masseuse work so hard trying to get a drunk guy to cum via a HJ or get him hard enough to shag...so instead I spare the girl the torture and ask her to lay down for a nice daty as a gift for her nice massage work. Then I would use the entire HE time to take as long as possible to get her to cum via daty (my movie trailer) so that she would be begging for FS on my next visit.
With some of these masseuse it is not so easy to pull off a great movie trailer. A movie trailer full of great special effects (daty with fingers penetration allowed to stroke and caress g-spot) is the best but sometimes I have to work the romantic tear-jerker angle movie trailer (a long 15 mins or more daty with no fingers allowed to penetrate...such cramping of my jaw I could cry) to get the girl to O.
