Why do men have nipples / breast? Is there a purpose? What is the purpose?

at conception there is no gender, gender is determined later in development

so u can suck em.

well men can produce milk in the right conditions just not as much

So that girlfriends have something to grab and twist without causing permanent damage when the men do something truly idiotic.

Don't know...why doesn't a chicken have lips? If you find out the answer to that one, then you'll know why men have nipples.

so my girlfriend has something to play with.......

for women to pull, tug on when we do something wrong. so i have been told and showed for many years.

In the beginning when we are conceived we are all the same alot of the same characteristics are on both males and females. We are given breasts before our male or female parts are evolved.

To prove that they are mammals, but I mean could you imagine what they would look like without them? That would be wierd...
