The smile of Eros

At 42 handsome, endowed Gunnar Lindquist has apparently achieved success in life. Married, healthy, respected in his own field, wise in the ways of the world, he nonetheless feels a mysterious need for something more, something different. Attracted to certain men, he has fended off their advances since army days but now be cannot resist doing some indiscreet flaunting and to allow himself to be seduced. Gunnar "comes out" and after deliberate experimentation in gay sex, sets about winning Jed, a spirited young straight with whom he falls in love-- until he is alarmed by the strange, phallic passion he has aroused in the younger man.
