>>3901379I remember reading somewhere that little penis and big balls makes the semen go furthest into the vagoo, but the opposite is best at displacing semen that's already in there and replacing it with your own.
And relative to our size, humans not only have huge dicks, but tiny balls.
So yeah, I guess we're the most competitive species
Also, I think you all overestimate the increase of pregnancy rate. Sure, it'll go up some, because there'll be twice as many who can impregnate and twice as many who can be impregnated, but people who aren't retarded will still use protection or something, and if a couple actually wants to have kids, they'll just divide the pregnancy instead of one parent give birth to all of them.
A lot of relationships would still have tops and bottoms, as some have pointed out, but the line will definitely be blurred. For example, now it's considered weird for a guy to like mlp or for a girl to talk about her shits/farts, but it wouldn't be a surprise for a top or bottom in this new culture to do those respective things.
And nudity will be a lot more accepted, because everyone has the same parts, but clothes will still be expected most of the time, whether to look professional or to keep warm.
The first generation would probably only accept nudity at beaches and the like, but afterwards it would probably be viewed similarly to if you had old shorts/sweats, messy hair, and a loose t-shirt: it's still not how you'd show up to work, but if you're taking a walk in the park or just got out of bed then it's perfectly normal.
