You’ll be fine, speaking from experience (I’m a guy) guys get just as nervous. Just treat them like you would any other person. Like its the first day of school and you just met this new interesting person.
Personally I just wing it on dates, but it always helps to prepare before. Every once in a while I like to write down different questions/ observations that will start a conversation. I’m not as serious as other people so my questions are things like, Do people really go to Pittsburgh when they die? (Get it? People are buried in the ground, pits) Then I can talk about traveling or something like that.
You’ll be just fine.
