Too much of an age difference?

Zoe
Okay so me and one of my friends have been hanging out quite a lot, recently. I can definitely see us dating in the near future. I've now really known him for three years. The only problem is that he's 18 going on 19 and I'm 15 going on 16. If we've known each other for several years, is that still too big of an age difference?? Opinions please 😌😘
