ReCreate YouTube Using WordPress

I want to find out how to enable my blog subscribers to upload their own videos. Basically, I am trying to have my blog act like YouTube. It’s going to be a website for short, hilarious videos- basically, short funny videos by lesbians. No porn, just fun.
Here’s what I did so far– I got the Buddypress plugin.
Given that on a WordPress blog, anyone can put videos in their comment on any blog post. Would it be possible to post all future videos as comments to the initial post? How about posting one video myself initially, then rigging it so everyone keeps commenting on it for ever after? Is that possible? Is there any way I might be able to do that, and restrict comments to just videos, so that we get no verbal, text comments? Any ideas on how I might do this? I really appreciate the help.
I want it to turn out like YouTube and I don’t know how to do that.

I want to give you a link to my nacent blog.?https://www.dykeplights.com
