Can anyone explain what knotted means please. I dont really get it

Dogs do it to keep there mate from running away and to allow them to release all of their "stuff" in to the female. It almost guarantees pregnancy.

When the alpha ejaculates during heat, the penis will have a bump (knot) around it to prevent taking it out in order to increase the chance of getting the significant other pregnant which lasts around 30 minutes if I'm correct. Damn I'm so rotten for knowing all this. Sorry for mistakes in my English btw.

Many omegaverse manga have the explanation at the strat, but couldn't find such a manga right now, but I did find a picture for you with explanation : https://78.media.tumblr.com/b1d3a62d2276276cabd5dbdff4ebffed/tumblr_oy3nv9X5te1wo8wp8o2_1280.jpg

can men in omegaverse control this knot?

Generally, they can control the actual act of knotting (first knotting their partner) but once it starts they can’t stop until it swells back down, at least not without the receiving partner being in even more pain.

Thanks guys! I swear people on here are so helpful
