caught up in the heat of the moment

i was at a conference this summer and met this grad student who is like 20 years younger than me. we got along really well over drinks one night and ended up back at my hotel room talking about everything under the sun. things got heated, i guess, and next thing i know we’re both naked on the bed, his cock hard against mine as he slides into me from behind. it felt so intense, our bodies moving together like that, skin to skin, sweat mixing between us. i could hear my own breath coming fast, him moaning above me, the headboard hitting the wall with each thrust. we didn’t stop until we both were spent and collapsed there on the sheets, panting heavily. it was wild, but also kinda amazing. afterwards he looked so nervous like maybe this was a big mistake, so i tried to reassure him that it was all consensual and i enjoyed every second of it. but now i’m left wondering if i took advantage or made him feel uncomfortable, which would be terrible since i really respect his work. what do you think? did i cross any lines here, or is this something both adults can keep secret between us and just let go as a one night thing?
