There’s no real strict definition for what is aro/ace, I wouldn’t agonize over it. I think what’s important is deciding for yourself whether or not those labels give you any sort of comfort.

‘Having a close friend you can trust’ definitely sounds like what many people would call intimacy (romantic or not,) but that might differ from your experiences.

Me personally: Sex is great and fun, but I can go without. Emotional intimacy is what makes a relationship feel profound to me. Having someone I trust to bare myself to, emotionally and physically - that’s what I want out of love.

There’s no right or wrong answer.
