sex on the first date

On Friday I went out with this guy. He was very nice and we definitely had a connection. We did kiss and we didn’t necessarily have PIV sex but we had oral. We were both definitely into it. However, these past two days he’s been kinda dry texting not a ton but the energy seems off.

Do you think he might’ve just lost interest in me because I let him do oral? If so I do regret it, because I am very interested in him and I hate that I might’ve ruined a good thing…

Pls give me advice or any input, thank you 💕
