A nymphomaniac is simply a woman with an excessive sexual desire. I think that describes Masha pretty well at this point in her life... There's nothing derogatory about it....
The only ones I've seen nicer in this apartment were Gina's... But that's a subjective call... I like the way Martina's move when she dances.... She can really make those titties dance...
Martina has no issues or hang-ups with her nudity... It's completely natural to her. She also went into the hall bathroom and sat on the toilet and did her thing without closing the door during the party... It doesn't bother her and she gives it no thought...
