I (20F) have recently moved into an apartment with my girlfriend "Maya" (19F). We've been planning it for a bit, mainly so I could finally escape my weird parents. We're far from wealthy so we tried to look for a place we could share with someone else, share the rent and all. We found this guy "Jared" (23M), and since we're built like a bundle of twigs we felt living with a man would be safer. Maya especially is pretty paranoid about home invasions, stuff like that. So we contacted him and started planning the move.
The apartment wasn't huge, Maya and I were sharing the only vacant room which meant we couldn't bring tons of stuff. Apart from that, there was Jared's room, a small kitchen connected to the living room and a small bathroom with a shower/bath. Overall pretty cozy, we both prefer smaller spaces. Jared and Maya quickly hit it off, he seemed like a cool guy, bit awkward but to his credit we were basically strangers. We finished settling down, him and Maya we're basically already friends (she's good at forming quick friendships, for better or worse).
First real night there, I quickly got comfortable. Nudity isn't really a problem for me, I didn't really think too much before putting on nothing more than an old t-shirt and panties. Maya, being her prude self, was hanging out in the living room with Jared wearing ample black pajamas. I joined them and we checked out the latest The Last of Us episode (good shit by the way). Maybe 15min in, I realized Jared was throwing quick glances at my chest and thighs, honestly didn't mind. But then I'm pretty sure I saw a boner as he crossed his legs, as if to hide it. I thought it was pretty funny I was having that effect on him, especially considering I was wearing more than I usually would. After that I kinda feel like teasing him, maybe wear a big long shirt without panties before heading to bed, but honestly he seems like a nice guy and I don't want to make him uncomfortable. What should I do?
