“How Can I Tell If I’m Really in Love.” Paramount. $29.95. This guide, aimed at teen-agers, has two main functions. One is explaining the distinctions between puppy love and mature love. Another is discouraging teen sex and explaining to teen-age girls how to ward off teen-age boys, who are portrayed as sex-hungry scoundrels. There’s commentary from hostess Justine (“Family Ties”) Batemen, Ted (“Cheers”) Danson, plus two experts and several high school students. The message, underscored by a soppy sound track, may be admirable but the presentation--too often cutesy and condescending--is occasionally a turnoff. Information: (213) 468-5000. 1/2
