Bloody hell, some serious overreactions here.
I do worry about the pressure on young people to do anal the way they do in porn. However, I doubt teens are going to go on Layla and look through the anniversary card section, come across this card then decide they should have anal.
Anal is not for me. I have no interest in trying it. I can understand that some people genuinely like it and not just because they are puppets and think they should because of porn. Lets give women some credit here.
As for it not being natural? I'm not sure putting genitals in your mouth is 'natural'. I'm not sure nature designed our mouths and genitals to go together, but they do and that is perfectly acceptable to the majority of people.
