For Karama, I'd say it's far more in social skills than in a trait like that. If he works on how he approaches them, he might find it easier to find a woman.
Oh, and one interesting thing about the shower! It's funny how that was handled so differently on my Cardassia. For them, replicator energy is apparently a greater concern, and takes more power than having running water and recycling said water. Same concern, different result.
