Maybe it's possible to "describe" your man through the other character(s) reactions to him, which might allow you to make more than simply physically attractive. How his body/eyes/muscles/cock/breath/voice/touch etc makes them feel....perhaps think about what it is that your female partners find attractive in you (surely you've asked? Grin) "I love your..." "I love it when you...." Your....makes me....."

Maybe. Or pick a film star/tv star you think is the right type for your story and try to describe him - but just generalise him enough to make him non-specific.
