Readers: Input Needed

A male reader has emailed me this question:

Any recommendations for making a latex mold of my cock? There seems to be a lot of products out there, but I can't tell the difference between 'liquid rubber' and latex and which will hold up better...

Sadly, this Steff knows nothing about manufacturing cocks. There are dryspells in my life when that skill would come in handy, no doubt, but nope. I know nothing.

I emailed a local sex shop that rocks, and they were stymied by the question. I've done an inconclusive web search, but to no real avail. Anyone able to weigh in on this one?
