Ey! I've got a lot of BL, though my stuff isn't Omegaverse, I'm gonna drop in some links to folks who I know are into that/making that!
First up, my stuff! My work is spicy, colorful, romantic, and comedic! I hope you'll give it a shot~
I also have WAY more comics and I make visual novels here:

I also just launched my first video series ever!
Now, on to other folks I recommend:
Gabi Wolf has several comics here on Tapas and is into omegaverse from my understanding! They have a comic on their Patreon that is such.
There's also Puck, who has Hive Heart here on Tapas...
And has just started releasing an omegaverse themed comic on their Patreon too!

And, my favorite webcomic of all time (it's not omegaverse) The Search for Henry Jekyll! It's a queer retelling of Jekyll and Hyde. It's not really "BL" but does feature male/male stuff so I wanted to throw it in there.
