Dating with ocd

I’ve started going out with a guy and i dont have experience in dating in general and I haven’t before and I have this movie like expectation of exactly how it should feel and it doesn’t feel exactly how I thought it would and now I keep questioning “I didn’t get enough butterflies when I hugged him I didn’t feel intense overwhelming joy does this mean I don’t like him” even though I WANTED to hug him and this keeps happening I’ll be sure I like him one day but then be like “I don’t feel enough butterflies,enough happiness,my heartbeat isn’t high enough“ and it’s so confusing how do I stop questioning and overanalyzing everything I just wanna date like everyone else but everytime I go out with a guy this happens and I always pull away and never end up dating anyone
