NSFW (If you want)- People in Generation X: Are we more sexually uptight than the older or younger due to AIDS education?

I caught a silly movie the other day.

The characters are trying to talk each other into being more sexually outgoing. A long speech is given wherein the characters argue that the older and younger than Generation X are way more sexually open because AIDS was so very scary in our formative years.

Is there some truth in that?

Older or younger people reading, have you noticed a difference?
