If it’s the case that the only evolutionary reason for large breasts is to better attract (some) men, that would be interesting.
It’s not like large breasts are more common than not large (unless you mean anything larger than nothing at all). I suspect there was a random mutation, and it didn’t hurt their reproduction chances but it didn’t help either. So you end up with a variety of breast sizes.
For some reason, only one ape species ever has non-small breasts. You never get large breasted gorillas, chimpanzees or bonobos even though they share 98% of their DNA with us. What is it about humans that means that that trait was evolutionarily advantageous? It’s obviously a feature with significant disadvantages, so what is the advantage that offsets that for humans in a way that it doesn’t for other great apes?
This might be 100% bullshit but an interesting theory nonetheless.
Gorliias, chimpanzees and bonobos walk around at butt height and see how strong a potential partner is by their butts. Since we started walking upright boobs are closer to eye level and have eveloved to resemble butts.

Do gorillas, chimpanzees, or Bonobos mate face-to-face, or doggy style?
For bonobos, a whole variety of ways and very frequently.
Yes
