Big big fan of things getting hot and heavy between Tony and Peter in the lab one night and Peter fails to mention that it is his first time. He doesn't feel like he needs to because Tony is so attentive of his partners, making sure they're stretched and enjoying themselves, plus he doesn't want Tony to start second guessing himself and stop because he thinks it is best for Peter. And why would Tony ever assume this guy is a virgin, look at him. There is no way this man has made it to his 20's and hasn't had sex yet. But then they have a later conversation and Tony is asking what Peter likes and of course he doesn't know, he has no experience except porn and some fanfiction. So Tony asks 'What have your partners done in the past that you've enjoyed then?' And Peter then has to admit it. Resulting in Tony being incredibly aroused about the fact he is the only one that has ever been inside this boy, but also wishing he could have made it more special than pinning him to a lab table. Although Peter thinks their first time was nothing less than perfect.
