Longer penises can theoretically place semen closer to the cervix, and thicker ones can “scrape out” rival semen (the famous “kamikaze sperm” hypothesis). Some primate studies show this matters in species with a lot of female promiscuity. In humans it’s debated, but it may have been a factor 100–300 k years ago when mating systems were less monogamous. -ai slop
