You’re going to get a variety of responses here. It all boils down to what you are comfortable with in your home. My AP has a boyfriend and the boyfriend has his own apartment, so they have no need to get it on at my place. If for some reason he needed to stay the night here, I wouldn’t really care as long as she asked me first. Now if I felt like he was staying the night so they could hook up because they didn’t have somewhere else to do it, I won’t be cool with it. My AP has also been with me for a year and half, so we have pretty solid foundation of trust at this point. I had another AP that did the tinder thing, and went to dudes houses to sleep with them. I let her know that wasn’t safe but if she was going to do it, she was not allowed to give out my name or address and the guys were never allowed anywhere near my home.
