What is the top/bottom ratio?

Im thinking of becoming a full bottom instead of verse due to having a skinny penis but wonder if what guys joke about is true and that they're a LOT more bottoms and tops. This makes me want to stay verse for more options but my penis and just how gays are ,this is not such a good option for myself esteem. I always get hit on by tops or verse who just want to top me. So what are you guys thoughts on the ratio? Would like some opinions so i can get a picture of what im expecting.
