It's impossible to avoid every possible trauma trigger when making a movie. The fact that some people might seriously be unable to watch sex scenes shouldn't mean we cannot make them at all. If sex is an absolute red flag for you in movies, watch PG-13.
Other example: My mom doesn't like violence in movies. (Doesn't mind sex scenes btw.) And that just means she can't (and doesn't want to) watch most recently produced shows. And that's just how it is.
Obviously there's a market for movies with sex scenes in them, or Hollywood wouldn't make them. You will just have to live with the fact that your in the minority here.
Writing stories/novels.
Chances are your initial expense will be zero. You most likely already own everything you could need. Almost everything available for purchase is unnecessary or completely ridiculous. Your friends and family won't even know what to get you for Christmas over this new hobby.
Fill your everyday routine with daydreams and inspiration, imagine scenes and dialogues while your mind would otherwise go idle. Stuck in traffic? Turn up the music and imagine something. Bored doing chores? Picture yourself as one of your characters. Annoyed by strangers? Put them in your story and let a piano fall on their heads.
I truly think everybody should write. It's such a delightful thing. Not to publish anything obviously - but because it's fun, it's easy and it's completely free.
