How important is a ass on a dude? I've been told I have a ass quite a few times in the past. I know and have heard before from this sub and other women that a ass is welcome and awesome but I want to know like does it compare to how much dudes love asses or is like a individual thing? 
Like I know every guy can appreciate a great ass and if one is had then it usually can be a huge deciding factor when thinking about approaching a women. 
I'm just wondering how important is is it specifically to women, like on a scale of one to ten? 
For guys I would (and I speak for myself and don't mean to group all dudes with my opinion) but I would say having a ass (as far aesthetically)  is not a need but it's a huge asset (couldn't resist sorry) and say it's about a 8.5 on personal attraction scale. 

Please don't take this as me being a shallow bastard that's only focused on physical appearances. I'm just wondering.
