I spend a lot of time in the gym and honestly I do it for myself but I'd like to be considered physically attractive to girls for my own ego, what can I do?

I know that girls get boob jobs if their tits are small, but is there anything I can do for a small dick? I want to be the average 6 inches and I'll be happy.

Also for my height it's about 5'8 but I'm down for leg lengthening.
