Paypal prohibits payment for tobacco and other stuff.
For adult material they want you to ask permission. They might grant it or refuse it, depending on lots of criteria. Like where your business is located and if you are a business and what kind of adult material it is. (This is speculation. But it obviously is possible, since even Steam accepts payment per paypal for adult content. So you might be too small, there might be tax issues and so on.)
