You shouldn't worry too much if you please women. I have 4.25" girth but I primarily seek sex for my own gratification, thus I have a body count close to 40 and most women have returned for at least a 2nd round if not more, sometimes I'm the one who drops them because I just wanted an easy fuck. If you want to give women orgasms easily then just give good head like I do, I do it because I enjoy it tho not because I'm compensating. Maybe if I really want to see a girl a lot I'll go the extra mile but yeah don't waste another second worrying about your dick just do it for yourself brother. And if they have a big pussy cant feel 5.5, guess what, they cant feel 90% of men so its their problem, fuck em
