<human>: Good morning. So firstly there are three girls living here and two bathrooms. I have the small one and the share the big one. Also, her boyfriend has been over since Friday afternoon. 

She and her boyfriend have had shower sex daily. It's actually what woke me up this morning. It makes me feel uncomfortable. The showers amphify noise, so you hear it even when your door is closed. My other flatmate also does not feel OK with this, expressing that it's very awkward. Other flatmate also saw the boyfriend naked because they were going to shower together and he lacked a towel. This is super not OK with her.

But is this an issue? Overnight guest are fine. So doesn't that mean we accept it to happen? I just.... they're not killing kittens or something. I have never had this situation before, so need to know if it's OK to ask her to stop or if it's out of line to ask these things since we allowed the boyfriend over.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: is it OK to ask my roommate to not shower with her boyfriend as it makes me feel uncomfortable and it makes the other flatmate feel awkward? Or are we out of line and disrespecting her guest to request this?
