I do sometimes think about what the ideal person would be like, must-haves and certain preferences. Though, it's not like I'd make a checklist over all the small things.

I'm looking for someone rather healthy in a physically sense, slim-ish body type. Cute face (very important and subjective). Boobs and butt doesn't actually matter that much, but I do still have a prefernce. Flat > huge chest, as massive badonkers is a turnoff to some degree.

Genuinely nice personality, relationship goals that align, open to trying new things, similar hobbies is always a plus. A certain strive to reach their life goals is important.
- I used to be goalless without drive and it was terrible, I wouldn't have dated me back then.

Showing vulnerability, great communication, lifting each other up and so on; everything a great relationship should entail. I could expand, but this likely already gives a decent picture.
