There is something inherently sexy about a three way.
So much willing manhood in such a well defined space.
Now don't get me wrong. Two men is perfect. Three is not perfect - it is extremely sexy it just isn't perfect.
There are certain things that two men can't do - at least not do simultaneously - that three men can do simultaneously. There is the conga line, the Daddy Sandwich, the 699, the 696 etc. There is even watching (but that is another subject.) Well you get it...lots of things to do.
But as my husband says "Why go out for hamburger when you can have steak at home." I personally think that sex with my husband - that "no-holds-bar" kind of sex where the earth shakes and the world stops, where any fantasy can be fulfilled on the slightest whim and without a trace of doubt or guilt - that kind of sex beats out any "way" including a "three-way."
