I think that #Nostr is not the right "platform" for paid adult content right now. If it gets more users that might change. So being one of the first ones to sell adult content might give you an advantage later on.

Speaking for myself:

I have never paid for nsfw content, I don't plan on doing so. With #Nostr the chances of a zap from me are a lot higher, but only if I really enjoy that note. The non-subscription model might be the future.

To your person (also just my opinion):

Just looked through your content, you have an amazing body but I really really don't like tattoos 😉 sorry
