In his writings he emphasizes the need to uphold precepts and to conquer sexual desires. This was also directed to laypeople. This isn't news to Chinese readers, but a western audience will probably not care for teachings on celibacy. That's for monks, not laypeople. However, he wrote in quite plain language the need to overcome sexual desire as a prerequisite for attainment.
You can't have your enlightenment while having an active sex life. This isn't unorthodox or innovative. Shakyamuni taught the same thing.
The American Zen image of being a Zen master while leading an "ordinary life with an ordinary mind" (with a girlfriend[s]) has a lot more appeal to ignorant audiences.
Could you post some relevant quotes? I have a couple of his books but they don't really go into the topic. "Orthodox Chinese Buddhism" mainly discusses the third precept and Buddhist views on birth control and abortion.
In "Attaining the Way" he writes:
Sex between married couples is not wrongful lust. Such conduct serves to maintain personal health and family stability, provides the blessings of children, and promotes social harmony. When people who are not married have a long-term relationship that is stable and relatively pure, this is all right too.
Since Sheng-Yen has been a key figure in promoting lay practice (and his dharma heir, John Crook, is a layperson) it would be interesting to know more about his views.
