I feel naughty visiting the boy's talk >.> Still, my husband is Ft? and is not comfortable with researching stuff, yet. I tend to check it out, plus, in case I ever need to go under cover as a guy in the future, I could use the ideas >.>
But yeah, I do when the toilet is cold or when I am wearing pants, I tend to stand up. With skirts or dresses, I always Sit To Pee. It isn't even that it makes me "feel more feminine" it just feels awkward.
No, in order to make this post somewhat useful in the FTM forums, I will say that a bunch of guys feel awkward using a urinal, so don't worry about using a stall in the men's room. Most guys will think you are just doing a "#2" to use an American colloquialism.
Sorry for interjecting into the boy's talk .__. I hope it wasn't too useless, though!
