Of course it has. I started watching porn when I found my pop's stash in like the 3rd grade. The previous year I had found the magazines, but then I found the videos...and it was ON!
Remember back in the days when you had a VCP (video cassette player) or a VCR with a "TAPE COUNTER"? I would use that tape counter to rewind the video back to the point I found it. It wasn't easy because when my parents were gone my snitching sister who was 4 years older was on the prowl. I don't remember the name, but the second vid I saw had Ron Jeremy and Nina DePonca, and the very first was "Play Me Again, Vanessa" with Vanessa Del Rio.
I learned so much, but being a smarty-art dude who had no game. I didn't get a chance to try it until I was 17, AND I BROKE HER OFF. Not many dudes can say they made the first chick they fucked cum, but I did. She KEPT my ass coming over from school as many days as I could.
Porn taught me a finishing move...THE SCISSOR. You can't go to the scissor first because that position (imagine two scissors trying to cut each other) allows for the deepest penetration you can get. So you are 80-85% in all the time and then BOOM hit her with that extra few inches takes 'em over the limit. I'm 34 now and I have been makin' 'em cum for 17 years thanks to porn.
I also learned how to eat pussy from porn. Some, shit, most dudes just eat the pussy wrong. First of all they don't know how to raise the hood. The pussy is covered the same way your dick is protected by foreskin. If you push that shit back you expose the clit, and THAT is where you need to be paying attention. If you don't raise the hood you are basically wasting time because the hood dulls any, well, much of the feeling. Hold the clit hood back with your thumb and lick the clit at a medium speed. You can't go too fast because you can't maintain it and you will tire yourself out.
Lick it, get a nice little rhythm going, and, if your tongue gets tired you can use your lips by moving your head side to side or stick your tongue out and just move your head from side to side. You can't do it for too long, because it doesn't feel as good as licking it and she could start to lose it.
By losing it I mean this, think of a car from 0-60. Fucking around when your tongue gets tired too long can have her going from 55-almost there to 40 or lower. You want to just give your tongue a break. You can also suck the clit at that point, because if you are doing your job she will be almost there in 5 minutes or so. After your tongue is rested, go back to licking and finish her off. When she starts bucking, don't stop. Wait for it...wait for it...she screams God's name... You can stop then, but I sometimes like to keep going to have 'em stuttering. If you are lucky to find a girl with an extended or large clit (like Vanessa Del Rio) don't be afraid, and don't make fun of her, either. That shit will be your best friend. The secret to fucking is making a girl cum, and the easier it is for you to make her cum the more return trips you will have. Girls with extended clits cum so easily it is a shame. And they cum MULTIPLY. DO that and you will have her legs shaking begging you to come back. You may never have to worry around pussy ever again.
If you are a rookie and your eating skills aren't quite up to par, you may have to use a finger as well as licking the clit. Put your finger in and curve it upwards like a hook. You should feel a "ribbed line" (it feels like really small ribs, I guess). Stroke that as you lick, that should get her there using both in combination with the other. She will cum if you are doing it right. You never have to taste anything, because no juices are up there. Completely mess free, well, mostly...depending on the girl. So no more milk mustache.
*************YOU'RE DOING IT WRONG**************
Inexperienced, or stupid guys do this. Think of a pussy like a tear drop. The pointy end, or the top of the teardrop is the spot that is the mist sensitive. The rounded end, "the honeypot" has a little feeling, but nowhere near the amount in the top. The difference is, you can make a girl cum never never even touched the honeypot.
Some dudes lick all around the honeypot and don't realize they aren't doing anything. At least not doing anything significant. Eating pussy the way I said above can have a girl cumming in 5-10 minutes or less if she isn't fighting it. Playing in the honeypot was get her to fake one just to get you to stop - No Bullshit.
Also, the honeypot is where all of the juices drain to, and a woman's cum can be pretty bitter. If you fuck around and make her cum or get close and the juices start to drain there and you taste it you may not eat pussy again for a while. So the message is, stay away from the honeypot. You never need to go down there.
Shit, thanks to porn I may be able to start teaching a college course
