First relationship help

so I’m talking to this guy.. and I have told him I want to wait before having sex ( something I’ve never done before ) and our first date was to the movies which was so sweet and he is really nice and then night before last he came over to my house and we just watched Netflix and snuggled because I dont think you necessarily have to go out for it to be a date. well I did give him head... VERY GOOD HEAD. he was grabbing the covers, toes curling, pillow over his face and he said I took his soul 🤣 not once did he ask for sex. I wanted to give him head. but my question is.

I really like him and this is my first time waiting because I want it to last.. so how long do I wait? do I continue giving him head? any other advice I should know?
