Anxious to see him again.. But too soon?

Annaliese
My supervisor from work had been quite friendly with me and i didnt think any thing of it until he asked me to go out with him. Hes only a couple years older than me, really young, after an hour of games at dave and busters we relax and start talking and he starts kissing me. I havent had an amazing kisser in like 2 years. So i really enjoyed the night with him and especially his kissing. Im anxious to see him again and i regret not making out with him longer than just that couple minute kiss, but how do i tell him i want to see him again with out sounding desperate, its just been one day.
