I have a son too, so maybe that colours my reaction a bit.
Two examples come to mind.
1. There is a poster that I saw in the underground arourd Christmas. It shows a woman from the waist to the middle of her thighs. Sh ehas on a red leatherl skirt that is being pulled up INTO her, well front cracks. It is a beautiful photograph and I am not a prude, But I did make an effort to catch my son's attention elsewhere as we went by it.
Another is a Renault commercial on TV.
The ad says NOTHING about the meritas of the car, but only shows various AS*es being shaken around to the song, 'Shakin' that as*.
It is sorta cute, but I again divert my son's attention when I see it.
ANd of course there is the commercial for a car.. some Japanese make I think, where there are several couples in a living room choosing partners for wife swapping by car key lottery. (I had to get my Beloved to explain it to me!)
It just seems that sex is a harder, less intimate thing there in the media. It's more about getting your rocks off than connecting.
BTW I would be livid about your figure! Tell his mates to keep their comments to themselves. But of course, I don't have so much to comment on...
