Where to get reamed?

Hmm, I am rather confused, I've always thought of a reamer as a cutting tool for making a hole larger, so I tend to refer to a crown race cutter, but then a frame headset reamer.

I was born in the sixties, though, so my understanding of, and assumptions about sexual practices is exceedingly rudimentary and out of date.

I'd agree.

Internal = reaming.
External = wanking facing.
