There is the issue of an orgasm before penetration, but barring that, does the length of intercourse have any bearing on reproduction?

OP thanks for making me search up this on Wikipedia. I guess this does answer the first question: premature ejaculation might indeed be the desired trait in most mammals...

I couldn't find anything about length of intercourse vs reproduction rates... The only thing I could find that are remotely related are one suspicious blog post and this post by Mayo Clinic. It seems that the sources I could find suggust it is a serious issue for self-confidence/sexual well-being, but there doesen't seem to be any documented fertility issues as long as it is PIV sex
