It’s not as if Hermione was a virgin, she’d spent nearly four years with Ron. But it wasn’t as if he’d been  particularly adventurous. If she were to have to describe it, vanilla cake might be the right phrase. It wasn’t that she didn’t  like  vanilla cake, it just wasn’t her first choice. Vanilla cake can be perfectly good and acceptable. There was nothing  wrong  with plain vanilla, but it was a bland, unexciting flavor.
