Mexico used to have a much larger output of films in the past. Those movies were mostly cheap and dull comedies, or groan-inducing melodramas. However, those cheap, dull and groan-inducing films actually managed to get people's rears into theater seats, so at least they justified their existence by being (somewhat) profitable. A select few maverick Mexican directors dared to make politically charged films in politically charged times in order to represent Mexico in film festivals.
But then there's movies like Educación sexual en breves lecciones, which fails as popular entertainment as well as an art piece (or as a sex ed movie). It's because of movies like this that Mexico's movie industry took a nose dive in the 90's. Who would want to waste their leisure time and spare change on this mess? That would just encourage director Alejandro Gamboa to do more like it.
So this is the story of Ana, a co-ed that somehow managed to stay a virgin until her early 20's despite looking like a daytime soap star and in spite of a secular mindset that probably rules out any chastity vows. Her dream is to find Mr. Right. Her bff Alejandra already seems to have found hers, but, alas, he's a two-timing womanizer that even hits on Ana herself at some point. A goofy male friend of Ana's want so badly to hook up with her, so of course she blows him off rather childishly, because this is her movie, dammit, not his. Anyway, Ana is hot for teacher. She engages in painfully cheesy secret admirer games that eat up a lot of time and go nowhere, and when that fails, she tries to literally jump his bones in his office. Alas, teacher's... ¡gay! *gasp* Goofy male friend confronts Ana with her folly and sermons her about dating outside her age group. Ana submits meekly to his Father Knows Best logic, and she finally relents. Ana, Goofy Friend (now Goofy Boyfriend), Alejandra and her Two-Timing Cheating Boyfriend all kiss in the end, which sound like an awesome orgy but it isn't. A pity. That orgy scene could have saved this boring, bland, moralistic wreck of a movie, and it could have imparted some of the sex education mentioned in the title but that was nowhere to be seen in the whole 94 minutes.
