Men like all breasts. That's a basic fact.
My own preference is for a 36b, but I can appreciate the beauty of the small to the large.
Natural only though.
If I were a man, I wouldn't like massively huge breasts, probably smallish to medium size, but the condition would be more important than the size. They should be pert, firm and symmetrical, not those droopy saggy monkey tits, with the nipples pointing south.
women are paranoid about their breasts and think men only want large ones, we like all breasts, and we love nice pointy nipples that we can hang our coats on!
we also like a woman to show a bit of cleavage, so we can have a good stare and drool.
i dont have a problem with false ones as long as they look good.
Velvetee and gucciman are spot on........it's the nipples that count. Just read the question again, do you mean breasts to look at OR breasts as a part of the foreplay. If the latter, then shape, size, nipples and consistency play little part as it is the response of the "owner" of the breasts to the act of caressing.
Hmmm, Any guy that says he prefers small breasts to bigger ones is lying.
There is nothing wrong with small breasts, but guys just prefer large to small.
Its like women who say they prefer short men to tall ones. They are full of it. They might be content with a small guy, but they would always prefer a tall guy...
