The WIP “In Stasis And In Space” has explicit content, but it’s MxM only, so you may or may not be interested.
“Supernatural in New York” has explicit scenes, but it’s being ported to Twine and thus will be continued on itch instead, and these scenes will be partly rewritten so you may want to wait. The author’s other WIP, “The Bastard of Camelot” will also have explicit content in due time, but it will be long before it comes before we follow the life of the MC and they are a child atm.
“Relics of the Lost Age” and it’s sequel (finished but not published yet) has explicit scenes, but it’s very very short and light, and I don’t know just how detailed you wish the scenes to be.
That aside, I know some project that will have explicit content, but that don’t even have a demo yet, so yeah, not ideal right now.
