Fascination with needles

This picture is a detail from my current series at mitchmen. It combines several of my long standing fetishes - nice round bottoms, underwear (white of course) and needles - and I suppose I should add quivering men to that list!

White underwear will be featured in my occasional 'In Praise of ....' articles before too long. The needle motif pops up in a lot of my pictures (notably the Cactus Kid picture story). I suppose there's an obvious phallic connection but I have never worked out where this particular interest comes from.
