I would say that 'it depends' on your kind of worship.
I'm not a Satanist, because I think it's as ridiculous as most other religions (hey - I am insulting you all equally at least) but I do know about some of the things they proclaim to do as part of their worship, for example, during a Black Mass, will copulate (go look it up) with a thing called a 'host' which I don't think I will describe here, but again, the Internet is your friend if you really want to find out.
This kind of worship activity will almost certainly qualify as illegal according to that weird law that prohibits oral sex and sodomy.
