I prefer fem mc, theres an oppressive mundanity to the way stories go with male mc. Harems are boring.
Having the possibility of the playable character be coerced into sexual favors or servitude works well for me in games, and while it's really common with fem mc the male mc games that allow that are some awful tower of trample inspired feet sniffing sim or sissification games that are often formulaic and mean spirited. It feels more natural to get that content with fem mc.
Some of the best games ever made are fmc, a dance with rogues, violated heroine, clymenias steam girl game, etc. You wont get same experience with the typical male led games as lots of content is simply not in that wheelhouse, like a npc imposing their will onto the mc pushing their sexuality onto her.
