Yes, yes it does.  Anyone who says otherwise is lying.  Why do you think that humans have the largest proportionate penis size of any animal?  There are lots of reasons penis size matters.  Confidence.  Men with large ones often are more confident, resulting in more experience, resulting in more confidence and more skill.  You can be too big, but it is rare.  Women’s bodies are pretty flexible.  Large ones are a turn-on because they stimulate primal hormones.  They seem more masculine.  Women like big ones for the some of the same reasons that men like big breasts.  They are hot. 

But what about how you use it?  Well, that is true as well.  In fact, smaller penises are better at stimulating the g-spot.  They can also be more comfortable in the positions that are most likely to make women climax.  Men with small penises are also often better at stimulating the clitoris because they practiced more and paid more attention.  They weren’t all busy shoving it in and hoping to make the girl scream from the size of it.  Sure, it is all great to scream because you filled up with a huge member that almost hurts, but it is even better to scream because you are having an awesome orgasm. 

So my advice is the same for all sizes:  learn how to use your tongue!  The truth is that more women like receiving oral sex better than any intercourse position.  Most women can’t climax during intercourse, but they can with through oral or manual stimulation.
