I'm a girl so I'm not the best judge but I thought the girls looked attractive (not more than any in the crew) but acted skanky. I just can't see say McCoy being attracted to them.
If its just about looks then there's Rand, Uhura and practically any Yeoman. Maybe Mudd's women sultry poses and availability attracted the men.
Not sure about "skanky," but Ruth wasn't my type and the Magda actress was really bad, so. YMMV. Also, the casting of really attractive guest stars (male and female) reached ridiculous heights in some of S2 and particularly S3. Anyway, I do like how with Eve it turns out to be all about self-confidence, or whatever the show is trying to tell us at the end.
