The payment processors will shut you down even for your first payment if it's for porn. More likely - you'll never get to a first payment anyways, they won't sign the contract.

If that was even occasionally true, the tons of paid porn sites wouldn't exist. The fact that they both exist and take popular cards tells me that that cannot possibly be true.
There are special payment processors catering to porn/etc, but the problem is that they require extremely large collateral and have other unusual requirements that are untenable to new businesses. Most probably they won't even talk to a startup (I tried, didn't get a reply). There's a reason why startups like OnlyFans used normal payment processors and tried to convince them they're not porn instead of beginning with these specialized ones.
Edit: BTW, a large portion of seemingly independent porn sites are actually run by only few companies. Especially the Xvideos corporation.
A payment processor is an entity that handles bureaucracy. It's not a piece of software you can run and forget about. It is many people working around the clock taking phone calls.
Not doing something because you might get too big is not sound reasoning.
When you get too big, that's the time to worry about it.
