Hey, no worries about taking up my time; I'm glad to help however I can. Just a heads-up, though: I'm going to be pretty busy for a little while starting tomorrow, so I might not be able to get back to you again until after I'm finished up with that.
Anyway, I'd like you to clarify one last thing about your preferences: when you say minors, does that mean any character under 18, or just outright children? Like, are you fine with teenagers who actually look and act fairly mature, or is that still off-limits?
Once we've cleared that up, I think I'll probably have a pretty good idea of the sort of things you'll like, so I'll put together a list when I can.
Other than that, there are actually a couple of recommendations I can give right now based on your other reply, although you may already know about them: Third Crisis (PC/Android), and Raven's Quest (PC/Android) both have female-protagonists, offer a ton of content, and are mostly/completely free.
The only content (so far) in Third Crisis that requires the "full" version are some "accessories" (cybernetic "enhancements" and outfits, which DO affect available scenes, but aren't strictly necessary) so you won't be missing out on a ton of stuff.
Raven's Quest in particular seems more tailored to the female audience, with its eroticism coming more from the descriptions of the events than from the visuals. The visuals themselves are still quite nice though.
