If you mean literally standing over her, yes. At the very least it's impolite.
There's nothing wrong with that, I do it all the time.
Well I do. I think she's a lovely woman.
Well...No...But only if she is on the lower floor....<br />
if she was in the lower bunk...Well then you do have a problem
YES!....You are sick!
I take it you mean with her in mind, I would say no. We can't control the people we find attractive. Now if you started a sexual relationship with her I think that would be wrong.
If you are a mastur-de-bater, who's gonna know what you where getting off on. This is one of those things, that I feel no one can morally judge. Judge not, less thy self be judged.
