Mia, I just want to say that you should never feel pressured into doing anal if you don't want to. Anal intercourse is the #1 cause of STD transmission. If it isn't obvious, I want you to have a long career, so it's in your best interest to look after yourself, which you are probably doing right now and will do so in the foreseeable future. Should you ever decide to do anal, make sure you trust the performer you're working with.
I hope you have a fruitful and enduring career doing what you like best.
