23 [M4F] Breeding and sperm competition

NSFW

There's a fact from evolutionary biology that I have always found inexplicably super sexy. From Wikipedia:

This research showed that, when combined with thrusting, the coronal ridge of the penis is able to remove the seminal fluid of a rival male from within the female reproductive tract. It does this by forcing the semen under the frenulum of the coronal ridge, causing it to collect behind the coronal ridge shaft.

And it just stacks up--so much of our anatomy, behavior, and identity have been shaped by evolution to make us the perfect breeding machines. That part seems to be relatively well known and common in the annals of NSCW Reddit. But the part that makes my heart race and my brain go wild is the idea that that's not all. It's the idea that not only are we built to breed, we are built to outbreed every other person on the planet.

So, if this topic makes your heart race too, I'd really like build a roleplay or just chat about it! I want to focus on how my fit sperm are going to win the race to your egg and breed you with my superior genes; fill you up so well that you know no other men could possibly compete to fertilize you. If you're into it, maybe that includes me using my superior cock to pull out your boyfriend's or husband's cum while I'm at it. I would really like to do a roleplay along these lines, but I'm open to just chat too if that's what you want. Either Reddit chat or DMs are fine! So far, I've obviously written this as if you, my partner, could get pregnant. But if you are a penis owner, maybe we can chat all about how I might do this to your girlfriend, partner, etc too--about how much more powerful and strong my sperm is. I'm very open to including any of your kinks in this story. My only hard limits are animals, non-con, and actual violence.
