What is it being a side?

Hi guys! I hope y'all doing well.

Well, there was this one thing popping around my mind - yeah "CONFUSION".

Nah nah nah, it's not about my sexuality or orientation - whether I'm gay or bi or whatever the shii it is.

Rather, this is about my sexual preference or what you call it "position".

A flashback, a year ago I realised that I'm not straight. When I realised I was a bisexual, I thought I would be a "🔝" (without any experience lol) cuz I thought it's just a normal and I am not interested to get fugged by anyone.

But months passed by, again without any experience, I slowly realised that I'm not into anal that much and days passed by, I realised I'm not an anal person at all. That's when I came across that I might be a "side".

Side means a person who is into every sexual activity except anal intercourse.

But what confuses me is this - I know that I'm not an anal person. But I love to do other things that a "🔝" does, like receiving fellatio etc etc (again I don't have any experience lol). Now I really confused that is it possible to be a "side" who can also be a "🔝"? Cuz I heard about vers and also vers🔝 and vers⬇️ but not in side. That's what makes me confused. Is it possible? Is it real?
