I think im too small to be a top

My dick is like 6 inches and decently girthy but the guys I hit up on grindr always either say its not enough or the bottoms have bigger dicks and it makes me feel insecure. I haven't topped since hs and I want to again because I love it. But it's really difficult for me cuz my dick is small. Idk what to do. Also im a pretty big dude. 6'0" 225lbs
