Can someone briefly explain the difference between playing as a male and female character? Thanks.
The difference is only in the sex scenes, not in any other game mechanics.
That being said, i would highlight 3 main things that both MCs have in common:
1. Check the tags. All of them are in and more.
2. Sex in this world is very much a free for all.
3. Any scene is up to your choice.
So, the main difference in short is that Male MC goes around and finds hot women and cute monstergirls to fuck with the option to get pregnancy scenes with several party members.
But Female MC already brings one hot woman to any scene, so everything that moves and even some things that don't are on the table, so to speak. Everything.
Overall, neither MC is vanilla, but FMC tends to be more extreme in the kinks. Almost everyone here replayed this game multiple times to see more scenes, and it's worth it if you like your first play through.
