I've been watching porn online since about age 16 or 17 also... and in my opinion, things have changed.

I've noticed two things specifically. 1. Almost all the girls are shaved bare (no pubic hair at all.) It used to be some shaved some full muff, some trimmed into neat shapes, etc, with pretty much a mixed bag of what you'd see. But now it seems like everyone is shaved, and if you want to see pubic hair you have to actively search for it. Sign of the times maybe? When I first met my husband, I actually shaved because I thought that is what was expected. He was surprised, as he'd never had a girl friend who shaved before. I no longer shave because it's uncomfortable, and hubby likes my little muff anyway

2. So much spitting! When did it become okay to spit on your partner? Porn (both professional and amateur) seems to contain so much spitting, and I HATE IT. It's so disrespectful and just gross. Who wants to be spat upon when they're trying to enjoy sexy time?! YUCK!!!! (For me at least - no judgment if someone else likes it). But its a problem for me, because every time I see it I get turned off immediately, and it seems to be in every video I find... I'm not sure how to filter that out in searches. sigh.

Rule 34 definitely applies! If you can think it, it's out on the internet somewhere. I've noticed quite a few more fetish sites and things cropping up. Or maybe I'm just getting better at searching. But it seems you can find things that run the scale from mild to wild and everything in between.
