Very interesting certain point of view! ;) I’d point out that the characterization of sex in Star Wars is probably a bit unfair though. To be honest, Star Wars as a franchise mostly just avoids sex, as it’s far more interested than Star Trek in being an all-ages property. So it will portray romance from time to time, as that is a great general motivator to heroes, but it never specifically portrays sex.

On the other hand, if Star Wars does spend a lot of time addressing love, it’s in the implications as it relates to religion. This is another area that Star Trek handles far more differently than Star Wars. Typically, when Star Trek portrays religion, it is focusing on how its rituals affect a society, and on how the beliefs are not science-based and what effect that has. Generally, Star Trek exposes the negatives and drawbacks of religion (though admittedly not in 100% of stories).

Star Wars, by contrast, has a much more balanced portrayal of religion, as it’s central to the entire series. One aspect is the very Buddhist idea of a general love for all, but a dispassionate ability to not love one more than all others. Jedi are meant to be like enlightened Buddhist monks who are able to serve the people by having attained this point of view, and their non-attachment is certainly not meant to represent a general attitude that the rest of the universe shares.

For those non-Force users out there, there’s certainly no indication in the movies of some sterile society that has adopted non-sexual reproduction. The one relationship that we’re shown in the films goes through dynamic changes, as does the audience. Essentially, Han and Leia’s relationship starts off as a schoolyard flirtation, then becomes a young adult confused passion, then evolves into a deeper connection, and finally becomes a mature relationship based on putting the good of the other before your own. Sex is basically kept out of it, and sure, there are still some weird elements baked in, but it’s fairly normal for family friendly fare. (Say that 5x fast!)

Now, if you wanted to write about how Spielberg and Lucas have daddy issues that have affected everything they’ve written (including the relationship/sex dynamics) then I’d be really interested to read that piece!
