That's definitely an interesting predicament.
I do want to congratulate you for being open enough with both your roommate and her boyfriend to let him express himself through nudity. Most, if not all nudists will remind you that nudity itself is not inherently sexual and amongst accepting individuals can be a fun and comfortable way to live.
I would say your issue can be looked at in two ways- one, you're discovering something about your own body and self that you'd like to explore. To which I say "go for it!". Spend more time in places where nudity is accepted, change rooms, saunas, or nude beaches. Feel your way out with these experiences and see where you may be comfortable going bare.
Perhaps at some point you can sit down with your roommate and Chet and tell them he's inspired you, and how you'd like to also experiment with nudity around the condo. They may accept the idea OR reconsider the flexibility around clothes that Chet has enjoyed.
On the other hand, you may be developing sexual feelings for Chet and or your roommate -what with nudity bringing to mind all the usual sexual connotations. It doesn't have to be about homosexual interests per se as you may just enjoy seeing a naked person, or enjoy the shame of gawking while dressed. There may even be a residual excitement being around a naked person, because it typically means you too will soon be naked and sexual activity is about to happen. Your continued cover may just be a constant tease for your overstimulated brain.
In that particular instance, I'd say to respect Chet and your roommate and do not make them part of your developing kink. Its important to take Chet's nudity at face value as non-sexual, and not to try to change that. Of course, if they make a move...
So as a whole, I'd say my advice would be to explore nudity and kink on your own, see what you're comfortable with and find partners who's goals match your own. And if you do go the route of becoming a "home nudist" around friends, be sure to keep things respectful as to not cause harm to others or you may find yourself looking for a new place to stay.
Good Luck
