Looking for advice

So I met a guy online a couple days ago and we seem to get along really well, and tonight he asked me out to dinner some time. I have no idea what I'm doing though.Just a little background. I was raised in a religious family and homosexuality was frowned upon big time. So I never got to experiment. I actually have never been out on a date with anyone before so this is my first time.So if I want things to go smoothly what should I do? I know to just take things slow and ultimately I should just treat the first date like I'm just hanging out with a new friend, but I just want to know if there are any tips you can give me. TIA
