Apologizing in advance for the indelicate nature of this question.
Going tinkle alongside other women in the ladies' room makes me aware of the difference in sound since unfortunately my SRS has had to be postponed because of no money. I keep noticing that apart from the tinkle itself, there's an additional hissing sound to women's streams. I've been trying to guess what difference in the shape of the stream (or else acoustics) could cause that. I think a lot of the difference has to do with the shorter urethra. This also allows it to come out faster and therefore louder. My tinkle is muted in comparison to other women's. I also have to take twice as long. I suppose it also takes me longer to complete because I can store up more before going.
Maybe I worry too much, but I hope the audible difference doesn't out me. I can't make it hiss at all, I can never make it as loud or as fast as in the neighboring stalls. When I go at the same time as a girlfriend, she always finishes up in half the time and stands near the door waiting for me.
I guess the only conclusion is: It bites being unable to afford SRS, I get more impatient for it every day.
