Alexithymia often means difficulty identifying and putting emotions into words, with thinking more turned toward the concrete. It is not a diagnosis on its own, and it is not an absence of feeling.
On Atypiklove, you can list alexithymia on your profile and explain what it means in your life. Another person concerned may understand part of the experience while still having a different style, pace and needs.
This community brings together people who use the term for friendship, dating or conversation. Nobody has to apologize for a trait, but clear explanations still help people understand one another.
