It's as old as time; the search for a hot juicy cock. I really wish the internet had smellovision, or aura-vision. Pics don't always do the hunt justice.
Having scoured the realm for men, I've often found that a face to face interface far exceeds the most graphic of BigMuscle profiles. Once you get a man's scent under your nostrils, a tiny part of him is in you.
And that's the eventual goal, ain't it?
Until the day man musk is downloadable, the machine may do for window shopping, but nothing beats meeting for meating.
