first time dating

hi guys. i need a little bit of advice on something. there's this guy that i've recently just started to date and i truly like him but for some reason i feel confused about him and where my feelings for him stand. i know that on the second date when we had our first kiss, that felt really good and nice and it's we connected emotionally bc i clung to him a lot closer then i did before but after our third date which we had last night, i feel a bit confused. i know i like him but idk if im just afraid of being hurt or let down or be used, much like i have in previous situations where guys have told me they "liked/loved" me just to get to see me naked. i trust this guy so much but idk if my insecurities are making me not believe him.
