I want to know if as a guy wondering what it is like to have breasts feels like?

Ones wondering is not going to directly affect the condition/growth. It is natural. Whether you wonder or not, it is natural and automatically grow along with bodily growth. We have no special or specific role to play in all these matters. To the best of my knowledge, belief and experience, there is no such physical exercise which can alter your present size. Please don't believe the rumors spread by mischievous people and unscrupulous elements in Society about such things. They promise to bring the moon. They suggest some lotion, which does not work in many cases. It is all hundred percent unalloyed lie. Don't believe the false words of such bad characters in future.

In any case, rest assured, it will not have any effect on males.

If they're implants, they're hard. If they're real they're soft. Most boobs that I ever felt were normally cold. They feel really nice because you don't have them. There are also ugly boobies that feel like flesh sacks. Yuck. If they're young and firm it's all good.
