Most people here are acting as sex (or speaking or singing about it) is something bad or disgusting. o.O
I don't get that, sex is a part of human life and it can be absolutely wonderful.
There are so many ways to write and sing about sex as well. It doesn't have to be explicit or dirty or anything.
So yeah, I think Ayu could do it if she wants to. But I don't think she would, cause it's not part of her image and most Japanese surely would be taken aback by it. Just because it's not the Ayu they know.

But I do believe that Ayu could write about something new for her. Pressure for example or Workaholics or something like that, she has enough own experience with that assuming that she's one as well.
Or the wish to have own children or something different. There are still some things she could write about and she would be able to include her own feelings again like in the past.
