Will I regret?

I lost my virginity on Friday - barely 3 days ago - with a guy I had met on the Saturday previous, at a party. We had spoken every night ish since the party and he invited me round his on the Friday. He did make me feel wanted, safe, comfortable and not insecure at all which in reference to that he couldn't have done better; even after all the blood🔫. However he has barely messaged 3 words since and has told mutual friends that he doesn't want a relationship at all as he has just come out of one. I've never been in a relationship and may want one but that wasn't the complete aim yet I would not class myself as a slut as he was also the first person to go down on me and finger me. I'm the 7th girl he's had sex with, but the first to give up my virginity. I turned 16 in September and he is 16 but the year above. Will I/ Should I regret it? 
Sorry for the long paragraph I just wanted all the facts out.  xx
