Do size of dick really matters in sex relationship?

Medium would be best.

It ain't the size of the tool, but the skill of the craftsman.

7.5 inch is good basic length, depending on thickness.

Average

Average is best of course.

Despite what men sometimes like to believe, it's better average. So not small. I used to be MADLY in love with a guy, but I couldn't help noticing that it was small... and it gave me a feeling that he was not healthy. A good erection, average in size gives a woman more pleasure and the extremely sexy impression of strong heart pumping blood.

It's all about what you do with it.

Its not like that, size doesnt mattr a lot, girth does bcoz, women's sensitive part lies just upto 3 inch depth which could satisfied by small dick except microdicks. stamina and girth is important bcoz girth helps in the rubbing and gives pleasure to both and stamina helps u to control ur orgasms. The most sensitive part of the dick is the cap on top, it is responsible for the sexual experience. Thats why the guys with big cocks feel more pleasure during sex as the interaction organ is greater in size

like 3 inches over avarage

should not matter to you, as long he hitting that right spot.

Average or slight over average is perfect size.

Yeah. But if you have a big one like me you can force them to orgasm whether women say its TOO BIG, the real decider is the pussy itself.
