Hickey

So I’m 14 years old and I went out on a date with my boyfriend who is 16. When we were out, we made out quite a bit and then he gave me a hickey in the worst spot possible. When I got home, I covered it up with makeup which worked. But then when I went to church today my uncle yells “is that a hickey” I went into full panic. My grandparents, my aunt, my whole family now knows that I got a hickey at 14. Any advice?
