You're definitely right - if we both love each other, the relationship will obviously be successful no matter what my size is. I just want to be able so satisfy all my partner's needs. I would feel insecure and sad if I knew that the person I loved was not sexaully satisfied. I want to be able to please that special person in every way - I dont want her to compromise in any way.
And can I add one more thing: Even though 5.5 inces might be the scientific average penis size(which I have some doubts about, but I will concede that point...), popular culture has determined that average penis size is larger than that and much closer to say 6.5 inches(this is at least the case in South Africa, where I live). This means that even though my penis is technically average, my partner will perceive it to be below average. Not to mention dissapointing, considering that popular culture has also determined that tall guys with large hands and feet have large penisses, which is obviously not the case with me.
And remember, the first time we have sex, she probably isn't going to be in love with me yet...
