Hmm, I guess sleep talking could be an issue. I sleep talk but the only reason I know is because of my BF. It's actually funny cause I'll ask him questions and he'll think I'm awake and then say all kinds of weird stuff. He said once he even had a conversation with sleeping me. But, if you change your voice, it shouldn't be an issue. I'm lucky in my voice is andro at worst and pretty femme or high-pitched at best. I believe it's like 170 MHz normally but I can take it to 220 by a simple adjustment, i.e. trying.
But yeah if you sound like a woman all day and then turn all barry white at night that could be an issue. I guess get your own room. I was in a really nice hotel a couple months ago but that's just cause the guy wanted to screw me and had roomates. Then he couldn't even get it up. My BF makes fun of him all the time for not being able to get it up, cause we were like on a break or whatever. But we have an open relationship. But I never even thought of this whole sleep talking thing, so thanks for adding another trigger, JK LOL
