OK, I dumped all the links I have, sorry for the mobile bookmarks but I'm also quite lazy.
Some of these are hit and miss for various reasons but I like the last linked video, because in her second play through she is quite surprised how she can see herself shrinking.
In another one of these the woman specifically mentions Talk To Me which is a infamous GTS video because it's a very old movie that has a man shrinking and pleasuring his naked girlfriend/wife and shows a hell of a lot for a B&W movie.
