Search Results: going to the bathroom together

So, my boyfriend and I have been together for 5 years and live together. A number of our friends live in different cities, so when they come to visit, they usually spend a few nights at our place.

My boyfriend has this one friend (female), and I'm "friends" with her too, in the sense that we hang out all together, but I don't really hang out with her alone and we aren't very close.

When this girl spends the night, she sleeps on our couch in just a t-shirt and panties---fine, whatever you're comfortable sleeping in. But she spends quite a bit of time before going to bed and after waking up walking around with no pants on, and if she showers, she'll come out of the bathroom and walk around in just a towel. I'm not really a jealous person, and I'm not worried about "Oh no, my boyfriend is going to be looking at her," but it does bother me in the sense that it just seems really tasteless.

I know people have different levels of comfort regarding nudity, but I just think that if I were spending the night at a couples' house, I would be a bit more modest if I didn't know how they would feel about it.

So girls, how would you feel if your boyfriend/husband had a female friend who did this?
