It is all personal preference, bottom line.
And teenytoona, maybe you don't like the in and out, but that doesn't mean that all women don't! Yes, clitoral stimulation is good, but if the in and out didn't do anything, or didn't matter then we would all be lesbians.
You do have to know what you are doing. Technique and confidence matter, but size does matter. I don't care what anyone says.
Some women do no like a big penis, so therefore size matters to them as they will get pain from a large penis. And some women like a large penis and therefore a small penis would be pointless.
But, ultimately we cannot control who we fall in love with or the size of their penis, so no matter what the size, if it is true love, then it will not matter.
