age difference

Ok so I'm 22 years old and recently met this guy who's lovely but he's 18 and to me that just seems too young 😩 I've never been with anyone younger than me and never really wanted to as guys seem to be quite immature sometimes anyway, I have my life together I live by myself and work hard in my dream job and have a 5 year old daughter and he knows all this and still wants to take me out.  He seems mature for his age but what are your experiences with guys younger than u? Advice is appreciated ☺️
