If you're trying Flux, you may have used up the 100 credits (100 images) which are only replaced every 30 days.

The lowest cost plan is $16.00 / month for 3000 credits that expire if you don't use them in 30 days.
But what they hide pretty good is that for $9.00 you can get 2400 credits that do NOT expire. That's a pretty good deal in my opinion.

Look in the FAQs section under 'Can I get more credits' and there is a link to the payment page for the $9 deal.

I assume it can be purchased over and over again, so why get on a more expensive plan? Anyways, you're welcome!

Honestly, my thoughts on Flux is that you are beating a deadhorse with just the base models. There just isn't enough training data for NSFW and in particularly messy. The image output is worse than Bing and dalle3.
That's not to say Flux isn't a great model, the prompt adherence is only second to Dalle3 and the visuals are probably 2nd too. Flux however needs time for the community to build around the base models. It's only been 3 weeks and it's developed significantly already.
I would highly recommend training a model to enhance it and running locally, if not then either pay for the compute or go down the civitai route and generate flux there using the loras. Everything else is a compromise.
I'd even say ideogram's V2 model is better than the base flux models for wam, although it doesn't do nudity.

I'm not as technical nor do I have the time for working with a Lora or any of the other aspects of many of the options. I know I'm missing out on better results, but I'm happy with the style of images from Flux so far.

For example, I could never get nudity with Bing and had to upscale with Krea for anything close to a breast to be visible. I'm not so much of a pie-in-the-face guy as I am a full-body mess person, preferring nudity or little clothing.

Flux fills the bill for that style for my purposes, though I do appreciate the advice you share with the group, and who knows, one day I may venture into the more complicated methods.

One thing I did notice, is that Flex is horrible at wetlook. I'm not that much of a wetlook fan, so it doesn't affect me too much, but others will be disappointed.

Here are a few sample pics done with Flex and upscaled with Krea

For now, here is something I had always wished Bing could do, and I find Flex has no problem making it happen quickly and without much prompt work:
