"heterosexual sex is required for reproduction!!"
1 - wrong
2 - who cares about reproduction
did you take the same biology class I did? cause if I remember correctly you kinda need a sperm and an egg to reproduce. and reproduction is kinda the whole point of life on a biological level.
as a literal biochemist who works in academic research, I can confirm that straight people are absolutely unnecessary at a biological level. god bless.
God bless
