I like how you have this assholeish method of presenting your opinion as facts . <| sep |> Have you learned anything new ? Does the lion still claw at the rose ? <| sep |> If you view sexual activity as a single monolithic thing then I guess this makes sense . However , at least in my experience every sexual person has very different expectations for how sexual interaction will take place . People who are both allosexual are frequently sexually incompatible with each other . Marriages and other long term relationships between allosexuals can and do dissolve because these major incompatibilities don ' t become obvious until well into the relationship . So really it seems in the best interests of all people to learn to express their expectations and elicit information about the expectations of others .
