Do you want to be friends or lovers with them?

More than 0 and less than 100. You are way over thinking this.

I think you are over analysing the whole thing @Lightlyseared. I would only use xx for people I am very close to though. I also wouldn’t go crazy unless it was my husband or kids. Do whatever feels right to you.

You’re over-junior-high-schooling this.

As per @roundsquare , You are way way way overthinking this.

One looks like a typo, two looks good, three is sexual, four is too many….so two.

I don’t really think it matters.
Two seems to be standard, though. Myself [and most of my friends in the US] usually do ‘xo’ to friends, and my friends outside of the US typically respond xx, sometimes just one x.

It really doesn’t matter. I don’t think it would even occur to me to read into someone sending too many x’s or o’s.

It’s exponentially related to how many smiley faces you dot your I’s with : ) XXX000 XD 0.0 ;-p

I wouldn’t use any except for people I am related to, or wanted to be more than just friends.

Two? One on each cheek?
I don’t know.
