<p>It’s partially the sex issue yes, but I think it is also a safety issue. The RA can’t keep control over the dorm if random people are in and out at all hours of the night,and if god forbid something happens like a rape, it’s the RA’s responsibility to find out who did it and if it’s someone random and not even living there that someone just let in, then there’s gonna be a big problem. I didn’t like having guys I didn’t know around the dorm, esp at all hours of the night (yes occasionally I did see someone sneak in with their boyfriend or whoever at 3 am). I’ve only done it once and it was only because we didn’t have anywhere else to go where we could watch movies (and technically they came in legally, they just didn’t leave by the right time).</p>
