Eduardo is unable to communicate his dissatisfaction with the sexual side of his relationship with his partner. according to the text, what might be a common outcome in this type of situation

I'm going to answer this based on context, so it may not be accurate, but it's how I feel.

Eduardo doesn't communicate with his partner. He gets frustrated. Then he's filled with resentment. His partner is unaware. The relationship most likely won't be good from this point unless Eduardo learns to communicate with his partner. Otherwise, the relationship will most likely be out the window in a while.

Hope that helped! :)

Have a good day! :)

DISCLAIMER: ALWAYS. Heck with a reliable source!
