>>521 I don't think that's Little Hiddles. Cock socks are always flesh toned, the whole point is to remain invisible, it looks the same color as the jacket. There appears to be a lot of fabric getting in the way. Damn those hideous whispy asymmetrical dresses.
Here's a fun run- down of sex scenes. I haven't witnessed them but can account for weird flesh toned getups. If glueing is needed they do their own. Makeup artists do often have to cover bum pimples and correct tan lines so I'd say if you want a career where you can get up close and personal with stars, choose makeup or wardrobe. In stills photography guys also pad their genitals with white bread (minus the crust).
