Until I was about 14, I was terrified of having to someday give a guy a blowjob, and I swore I'd never do it because I'd talked to another kid online and he explained something about flaps that came up on it and it scared me to death. I've had several partners so far, and all of them have been circumcised, so maybe other ones do have weird flaps on them.
