Age gap 4yrs?

Ok so the past few months me and this guy have been communicating on and off he’s 23 and I’m 19 but he’s been a really cool to get to know but he’s been catching feelings and trying to pursue me I’m a jr in college and he’s in his career and i almost feel like we’re in completely different places so i said we could maybe date casually. He’s a sweetheart and is planning a date for us this week sometime. am i thinking too much into it Is 4 yrs really that bad? I don’t think I’d want him to be serious w me I’d rather someone my age and I’m also a virgin so i kinda feel like he’d have that experience over me any thoughts?
