Do you own a character you don't like, but can't bare to part with?Yes. X3 I have a number of those actually. Most of them were like...impulsive claims/form applications and I liked the character at the time, but now I'm just like..."Why did I even get this character?" X3
"do you think its okay to not have a fursona? or do you think everyone should have one?"I don't think it's really mandatory for a person to have a fursona.

Besides, you don't really need one. Personally, I just like have fursonas because they're a way of showing myself in a different way. X3
"do any of you ever get attached to your designs that you made yourself?"(like you were going to sell them but you ended up keeping them?)
All. the. freaking. time. 0_0 I even do this when I'm an artist for a species. X3 My custom Zver,
Arwen, I went into designing her with every intention of putting her up for adoption, but in the end, I just couldn't imagine her with any name but Arwen and I couldn't imagine her being owned by anyone but me. X3
