Abandonment issues ARE pretty repellent. But if you're preemptively repelling yourself from an imaginary dynamic, that's it's own issue. Most affection in sex is just normal humanity, not abandonment rooted. Ooh hey this might be a pretty good baby/bathwater example!
I’d be curious of your definition of “affectionate.” Can you be specific? For example, mutual eye-gazing— do you consider that affectionate? What constitutes “affectionate sex” for you?
The abandonment issues informed the ways I seek and give affection. Once recognized, I could work on the abandonment issues without losing the ways I enjoy giving and receiving. I could continue to be super affectionate and sensual without projecting on my partner.
