Relationship Advice

I think we are good friends... We perform a lot together. And I sometimes see him staring at me... And one time I had a really bad headache during a service and he offered to take me on a walk to get me away from the noise and music. Idk if he just wants to be like a big brother figure, or no. I really need advice on what to do.

So...I have this guy who goes to my church. I really like him. But the thing is. If I ask him to go out somewher. I would get made fun of. Because he is 4 or 5 years older than me. Also he might say no.
