Treat it like a spur of the moment whim on your part. You did him because he was there and he was hot and you enjoyed the connection. Treat him like a toy you had fun using and that if he wants to experience you again, he's going to have to earn the right.
On the first date, you know nothing about him. How do you know you want his love or respect? He might be a complete idiot. Get to know him before you do it again.
