Age difference

Omg girls I need help. If their anything wrong with wanting a guy who is 17 years older then you. I ran into an old family friend the other day on my 23rd birthday and I had such an amazing time with him that I can’t stop thinking about him. And we keep texting and talking. It feels so nice but I’m kinda worried about the age difference and what people would think like I’m 23 he is 40 😩 but he is so damn gorgeous and good and nice I can’t stop thinking about him.
