Input: I (19F) have been worried about my best friend and future roommate (18M) for a while. He, I, and our other best friend (18F) are all college "gifted kid burnouts". We were all very accomplished in high school (before we knew each other), but also all miserable and without social lives or romantic/sexual experience. My best friend made up for lost time and has hooked up with 30+ guys in the 7 months we've been in college. I've always had a shame complex about sex myself, which led to me promising to save myself for marriage when I was 14. I only took it seriously for about a year, but because those attitudes are still there and I had no life in high school, I'm still a virgin in every sense of the word.

I don't care if he's promiscuous, but the thing is that he has *no* boundaries whatsoever. He doesn't care whether we're in our dorm rooms, walking down the street, on a public bus- he will tell us all the gory details and not give a damn who hears. I don't have a problem with talking about sex (although there are some things I just don't want to hear), but I do worry that people can hear us in public and we seem classless. Between the hypersexuality and the burnout, being trainwrecks is sort of our "thing", and it's made us a joke to some other people (there's a story here, but I don't have the character space to tell it- if necessary, I'll elaborate in the comments). I'm worried that we're combining our worst traits together instead of our best.

However, my main concern is that my friend's behavior is starting to cross the line from scandalous to unsafe. Then again, meeting strangers for sex is kind of unsafe on its own, but on several occasions he's put himself in danger- most notably, he got drunk with a stranger in a city he didn't know and ended up passing out on a train and waking up in a sketchy area. He's told me that he's had sex without a condom a few times, but insists that he only does so with people who are clean and that "the risk is so low that it doesn't matter". Whenever I tell him that a few minutes of pleasure isn't worth his life, he tells me that I "don't understand and never will". I'm risk-averse, although not as much as I used to be. As I said, I also had some negative attitudes towards sex. I get that he probably thinks my concern comes from that, but it's really not about the sex, it's about the irresponsibility. He doesn't react well to anyone telling him what to do, and I'm not trying to judge him for his lifestyle, I just really don't want to see him get hurt. Am I right? What can I do?
