How can I let my boyfriend, who is 19, know that I'd like him to plan a date?

Hi! I'm a 19-year-old female, and I'm feeling a bit frustrated in my new relationship with my 19-year-old boyfriend, which has been going on for less than a month. We've gone on dates before officially getting together, but I was the one who organized most of them, except for the one where he asked me to be his girlfriend. Every time we hang out, it tends to be a spur-of-the-moment plan, and we often don't do much meaningful together. I really enjoy spending time with him, but I feel like there's a lack of effort being made to get to know me better. I've tried to express that I would love to go out on a proper date, like dinner or something similar, where I can just focus on getting ready. It doesn't have to be fancy or expensive. However, I’m worried that I'm not conveying my message effectively since I often struggle with communication. I'm also concerned about coming across as demanding and unsure if this request is too much. I would appreciate your thoughts!
