I have worked with females for over night and 24 hours shifts while I was involved with someone. She trusted me to be loyal and I always was. Believe it not, I am very professional at work. Any kind of hanky panky at work would lead to, and should lead to immediate dismissal from the job. YOU ARE WORKING! So unless your job is a prostitute or something, you shouldn't be considering these things. As with any relationship, you need to have trust. If there is none, then what kind of relationship do you really have? Always worried about where the other one is, what they are doing, who they are with. You see them talking to another person, and you get worried of who else they talk to and what they do when you aren't around. It leads to breakups!
Also, I am pretty sure you are supposed to have separate sleeping areas and bathrooms. One should not enter or use the others. At least in PA, it is a law.
