Size to me is really not an issue at all.
Unless the size is extremely big, and I'm talking about so large that it is physically impossible to have any kind of insertion (which I personally have never seen) it all feels good.
I have been with men who were extremely small as well as what would be considered as very, very well endowed and they have all felt wonderful.
After all...a finger feels damn good so why would a small penis feel any less good.
