Dating turned into just sex?

So basically, I went on a tinder date with this guy I'd been talking to for a week, we went for dinner and then the pub, everything was going really well, I was flirting and making low key hints that if it went well then I'd probably sleep with him on another date (not a hoe move just really into him) so later on in the evening we meet up with my sister and her tinder date, and he's telling them how he's really into me and how it's going really well while I go to the bar (got this from my sister) everything's going great. He walks me home and we're like making out the whole way, seriously flirting and if I wasn't outside I probably could have fucked him then.. a couple of days later he comes round, and we "finally" have sex, and it was amazing btw. But now I feel like all he wants to see me for is for sex. I know it's early days (12 to be exact) but I really don't want just sex with him, because I really do like him a lot.
