There was a discussion on Fetlife with the title „rimjob vs ass worship“ and the opening post says the following:

I think its interesting that people associate rimjob with a woman licking a men’s ass, but when we hear ass worship and facesitting we think about a man licking a woman.
why do you think it is like that?

I got a little furious just by reading that – please excuse my language – stupid question.
It’s like that because people watch too much porn and porn loves to use the wrong labels to better sell their stuff. However, I thought it fitting to publish my answer here in my blog too because I have to clear things up way too often when I get requests for facesitting or ass worship.

I see a big problem in taking rimming, facesitting and ass worshipping as the the same thing and it annoys me on a daily basis as I am really into ass worshipping.

Facesitting is – like the word itself says – to SIT on someones face. This can include more or less breath reduction and/or weight load. The persons face is an equivalent to a chair. And a chair doesn’t lick me; not anal, not vaginal. You don’t even have to be naked to do that!

Rimming on the other hand is clearly defined as licking someones anus. No misunderstanding possible.
To do that you don’t necessarily have to sit on someones face and you don’t you don’t the setting of worship to do it.

Ass Worship can be so many things. You can adore the sheer sight, you can massage, caress and kiss these beautiful cheeks,… and so much more.
It’s so sad that many people have such a limited imagination to think that worshipping only meens to stick their tongue between someone elses bum cheeks!
