So you agree that wanting to have sex with someone for intimacy, because you feel horny, because you love them, and because it's fun IS sexual attraction?
If so, what is asexual about Emma's experience then? What's missing that allosexuals apparently feel?
The metaphor about the baking buns didn't really make sense to me either. If someone baked me some buns and they looked delicious and smelled delicious and I knew eating buns was a pleasurable experience but at that time I just wasn't hungry for buns and wanted to eat some fruit- I wouldn't call myself "someone who lacks the ability to feel appetite for buns" I would just think "I'm not in the mood for this kind of food right now, I'll eat some fruit now and maybe later I'll have some buns".
It helps that I tend to have cycles where I get super into one kind of food and then go off it for a while.
That sounds like how Emma feels about sex too. It's ok to not feel like partnered sex for a while and want to masturbate instead. Even if you know you enjoy partnered sex.
The "split attraction model" seems like an unnecessary attempt to try and make out "allosexuals" feel a completely different way about sex than people on the ace spectrum, like saying demisexuality is a form of asexuality, when many people who don't identify as asexual find emotional intimacy is a core feature of their ability to feel sexual attraction.
Why is it that there's this perception that "allosexuals" just see someone on the street and feel instant lust and would jump their bones if they had consent? I know very few people who feel that way about sex. If any.
