Happy to hear you enjoyed it despite that! My inspirations led me to try and make games where the TG elements are a pillar of it over the core driving force of everything, so that's a good sign on that working out.
And yeah, I can be a but trigger shy on explicit scenes. They tend to be in the bad end scenes, or at least some of them, bar a few notable scenes. There's also an independent variable that accumulates from choices you make on making more lewd choices that will sort of passively opt you in or out of more explicit versions of some scenes. So while they're not numerous, there's a chance you may have gotten the less explicit versions by accident.
For music, it varies a lot. They come from licensed music packs and music from free creators that make them for games. There's a bunch of sources in the credits document, but if you're interested in any specific ones I can always try to direct you to the right place for where that's distributed.
