If somebody tell you this, don't believe in them. These type of men can be emotionally reached if you show them even one of your boobs. If somebody is really emotionally unreachable or unavailable, you recognize it after spending some time with them. And the more you get to know them and be aware of this fact, you start panicking and asking yourself 'WTF am I supposed to do now?' Worry no more, for I will tell you what you can do.
