will this change anything?

ive been talking to this guy since early july ; facetime, calling , & texting everyday.  we've been flirting and talking and all that getting to know each other , his birthday was August 2nd and he wanted to take me to Dave and busters for games, food, and drinks which is the first time we met in person the second date he took me to Fridays last Wednesday  , and the third date which was last night we went to the beach and it got very sexual in the back of his trunk, do you think that this will change anything between us? should i have waited?? opinions please , judge away i want other people's POV thanks guyss
