Sex on the First date

Melody
I am so embarrassed to spill it but I had sex on the first time meeting this guy. We started talking two days ago and he asked me to meet him for coffee earlier this morning but I fell sleep so he called me in the afternoon and invited me over. So I went there and we cyded, kissed and had sex :(
Since I wanted/want to date this guy I do think I should just let him know that I don't wanna be a one night stand or an occasional hook up :(
