@Aethelflaed‘s mention of blood brothers/sisters reminds me of a somewhat unrelated story.. but still illustrates how much things change in a relatively short period of time. I remember being in about 4th grade when my good friend decided we should be “blood sisters.” She pulled out a big kitchen knife, just in time for her mom to walk in, so she chucked it in my backpack which was nearby. The day went on, we forgot.. and you better believe I spent the next day at school walking around with a big knife in my backpack. I can’t even imagine what it would be like if that happened today. SWAT teams?
I’m not quite Gen X, though some people count it as the very last year. I was born in 1982, and I don’t know that I feel like it changed our likelihood to explore or be adventurous, sexually… but condoms and protection are/were a big deal. Of course, not everyone feels that way, but I would say that for myself (and most of my friends), having unprotected sex was pretty much unthinkable. You just don’t do that. But, I’ve had sex with strangers, and that isn’t particularly significant on my list of interesting sexual adventures in my history, so I think the only difference is in the use of condoms, really.
