Youthful or mature?

I had assumed the op meant, "do you prefer either or," but not to insinuate that they are mutually exclusive. Perhaps op would like to clarify

Well, I do think that youthful and then even mature is kinda how an individual would define it since those seem, to me at least, kind if broad. I'm probably just over-thinking it hahaha

In all honesty I'd have to say both. Because although you need to be able to be a bit childish and mess around. That is not always how things work. You have to be realistic and have realistic expectations as well as being mature in the sense that 'I'm an adult now, this is what I should be doing'. Time and place.. definatly.

To me it's all about balance and wisedom. Perfect partner knows when to fool around, and understands when mature behaviour is required!

Mature yet youthful. I like a lady who doesn't behave so childish yet is very open minded and likes to have fun every once in a while. I can't deal with too much energy though, it gets annoying to me regardless of how attractive I find the opposite gender. In fact, that eventually makes the girl physically unattractive to me.

I'm kinda a mix of both and try to be mature when I need to be, but I'd prefer my partner to be more mature and stuff cause I'm just a little subby freak x,x
