Dude I'm circumcised and I've always been happy and comfortable being that way. I love having a bare exposed cockhead as its clean streamlined sexual and manly looking. Not that I've got anything against uncut cocks quite the reverse!
As for the flap and holes I think that's a foreskin remnant. As for the circumcision scar. You will find many people will love touching and licking you there because they know its a highly sensitive place on a circumcised guy.
So chill out dude and enjoy life.
