I have scoured every thesaurus I can find but cannot seem to find a (single) word that I can use to replace 'embarrasing' to signify the opposite of embarrassing (as opposed to the lack of embarrassment).
i.e. "he's embarrassing" becomes "he's (the opposite of embarrassing)" as in "he is something (that makes me feel proud)".
For comparison, the opposite of 'it's cold!' would be 'it's hot!'.
"It's not cold" (or "he's not embarrassing") describes a lack of coldness that could mean it's hot, but doesn't really imply it's hot, per se.. as a stand alone statement, it suggests the temperate midpoint between hot and cold.
