Your theory makes perfect sense; that if the sex that takes place on the series was relevant to portray a developing relationship, then it would have followed the dramatic precedent of B7 and it would have been shown. But an obvious decision was made *not* to show sex on B7, probably because they didn't want to risk the possibility of exposing any younger viewers to it. This included heterosexual sex. The only implied 'real nookie' was shown in the first episode between Blake's lawyers, and in "Sand", between Servalan and Tarrant (and this reproductive was necessary as a part of the rather exotic plot, *not* to show a developing relationship between S&T.)

All of this hints that although your theory has impeccable logic, the producers chose to follow that convention in everything...up to and not including sex.
