Why the icky fornication scene with Cage being ridden by his pregnant girlfriend?

This is a Michael Bay movie. Michael Bay also directed most of the Transformers movies. In Transformers: Revenge of the Fallen a small chihuahua-sized robot dry humps Megan Fox's leg. It seems Michael Bay just likes icky. Goodspeed riding his pregnant girlfriend in The Rock is the least of it.

Because Michael Bay thinks that he’s being mature by throwing in a bunch of gratuitous sex and profanity. All he’s doing though is appealing to 12 year olds.

Because the bulk of the movie is a complete sausage-fest, with the only other female role being that of Mason's estranged daughter. Bay had to find SOME way to sneak in some sexy times and female flesh!

And to have some role to dangle in front of the wannabe actresses he wanted to bang. . Yes, Bay has that reputation.

So do you hate sex, women or both?

Pregnant women should be treated like lepers, not eye candy for the audience.

Not to mention she's wearing undies during this scene because she probably didn't want to show a gratuitous beaver when she hopped off of Nick's dong.

So many virgins on this page...

I could have done without that, too.

Them that can, do. Them that can't, watch.
