This is all coming from a guy without a big dick. I have had a couple of women basically say (nicely) they needed a guy with a bigger dick which in the moment isn't great but was reality. Too short, breasts too large, nose not right, heavy, skinny -- people finding out they aren't what someone is looking for just doesn't feel great but is reality. I'm not sure why I lucked out but I stopped caring about it pretty early on and had plenty of sex, then a good marriage and kids, then a good divorce and now back to sex. A good sense of humor, personality, intelligence, use what you have. There must be 100 ways guys screw up their chances and some of them are probably packing monsters. Good luck!
