Help ! Need Advice !!

I was out with a guy a couple nights ago, and the night started out AMAZING! It was our first time hanging out so he really wanted to get to know me and just chill . About halfway through the night He Kept tickling me even though I specified That I was not ticklish at all . One thing led to another and I was on top of him making out with him ! After some intense and heated making out he took his pants off and put my head to his penis, so I gave him a blow job , but during the blow job he stopped me , looked me straight in my eyes and started jerking off to the sight of my face ! It was super weird, But kinda flattering.. Anyways Him and I still go out every once in awhile to "hang out" and each time is better than the last ! The only problem is Im 15 ans He's 18 , I really like him and He likes me ... what should I do?
