Throwing pornx.ai into the ringer. It's what I've been using for a couple months now with their Gold premium subscription.
They have an undress tool which is the typical brush tool I'm sure most of you are familiar with. You can opt to pay for tokens just to use the undress, but the Gold subscription lets you use the AI generator which is good for face swapping your own photos into custom actions. Some actions are just completely broken tho but I think trial and error gives some real preem results.
Sorry if I sound like a fucking salesman LMAO, just trying to put my boys on.
