Why did he say he has to go take a shower after I said I've had sex with a Girl?

Basically me and this guy where playing never have I ever and the questions got little personal and he asked if I ever slept with someone and I said yes and he said no but he also replied to what I said with an eyebrow raised emoji and I told him I had sex with a girl not a guy yet and then said "I'm gonna go take a shower real quick" with a laughing emoji and left. Now I'm worried did I upset him?
