You do have some problems. My size, which is roughly the same as yours, is something I regard as a bonus, something that brings a smile to an experienced girl's face. But what happened to bring us together was down to me, and what happens when we are having sex is also down to me. Ten times as many women have gotten off on my oral sex skills compared to my cock size, and a few have openly (and I believe honestly) praised me for what we did together.
My standard script is oral until my partner comes, and then intercourse. With my wife, there's no question I know how to press her buttons, but with other girls I was generally pretty good. If the intercourse that follows is better because of my size, then that's okay, but for me sex starts when the first garment is shed, and it doesn't finish until one or the other rolls out of bed. Until then, the kissing, the cuddling, the stroking, the oral sex, the intercourse is what I call sex, and something I believe I am pretty good at too.
Women look for romantic men more than penis size, women love to be loved. Women truly ache to be loved and adored, and the more you know women the more you find out how universal this is. Romance is something that you can do any time of the day and any day of the year. Romance is also something that you can bring into sex, and most women go absolutely gooey when sex is warm and romantic.
