And what if he's not too big?
I don't know the other girls opinion in this site, but in the case of my wife, she had not been interested only in the dick sieze.
She had had a black boyfriend before me and she told me his dick was normal (perhaps no more than four and half inches) but he was able to make her cum quickly, already one minute or less. She told me this after one of our first times having sex because she had been having some difficults to get an orgasm with me.
They used to make the love in doggy style and missionary. When they made it in doggy, my wife turned so hot, and the view of Susan's butt knocking his pelvis, gave him a quickly orgasm too.
In missionary was more intense than we could imagine!
He was a little petite and thin, so my wife felt this position good and confortable. When he was lying over her, his head stayed near her breast which were licked by him at the same time he was fucking her, My wife turned crazy of pleasure and she used lock her legs wrapping them around his body, allowing her ex boyfriend obtain a deeper penetration. It was so stimulating for them and they cummed soon. In general she obtained her orgasm first although sometimes they got them togethers,
Just in one occasion he couldn't wait for her and cummed first (it was when they started their relation ship and they were knowing each others) but she gave him a great blowjob and his cock turned as hard as a rock again. They fucked hard and she cummed in less than one minute for first time.
Several times she told me how excited he could make her feel and the short time that she needed to reach an orgasm when he made her the love.
I think he was so virile and potent and he was a first class male don't needing a gigant size penis to get her an orgasm.
