I respectfully disagree, and return to Dingedhearts analogy about the pro footballer. You can coach an average man to be a better fooball player, you cannot make him a pro, it's the same with sex. With regard to my boyfriend cumming to quickly, we have worked on this together and things are good, however he will never be able to last like my lover, who can literally last as long as he wants, and he does, he cums when he wants to. I have never been with any other man that can do this. He is great at sex, it's a talent he has. He would be a pro footballer. You can also not teach or give someone a magic touch, you can teach a man how and where you like to be touched, but thats it.
The analogy of a pro-footballer is also wrong, and also irrelevant. Pro-football takes years of training, and given the age range that you can play within it means that you have to start playing and be given decent training when you're very young. That said, ANYONE who gets that level of training has a shot at pro-football. The development of skill is not based on some form of innate talent but deliberate practise. Given that there is no "age range" for sex like there is for pro-football, you can keep on improving for years to come. Your evidence is anecdotal, because the number of men you have been with is statistically insignificant - that is to say you haven't been with a large enough number of men to know if your lover really is one of a kind. The magic touch is not magic, but based on factors of physiology, and you most definitely can teach it.
Let me give you an example of something my bf has that my lover does not, and never will have.
My orgasms are far more powerful with my lover, but my boyfriends own orgasms are way more powerful than my lovers. When my lover cums it just kind of dribbles out, where with my bf, stand back ladies. lol I have never seen so much cum squirt out of a dick at such speed and velocity as it does out of my bfs penis. It can fly a good few feet lol and I dont know where it all comes from because he has small balls, although they are perfectly formed. This is a talent that my lover cannot learn, even though his balls are big.
This is one of the reasons I love giving my bf oral. I love bigger dicks, but I do love felating my bfs cuter and smaller cock. He has a very sensitive penis, this is why he doesn't last long, but this also means that he gets so much pleasure out of me giving him oral, I have to take things softly, and I get a massive kick out of giving him that much pleasure. My lover, well, his penis is not in anyway sensitive, I can do what I like to it. haha
My bf and I love to 69 with each other, because he cums quickly and we like to cum together, and because it takes me much longer to get there, this is what we do.
I know my man now and I know when he is going to cum, so when he reaches that point I will stop for a minute, while he continues. Then I will start again, and we go on like this. I stop and start and he will continue all the time. It gets him so exited that it gets to the point that I can only suck him for 10 seconds. I edge him, and when we do this, thats when he can really explode. lol He loves it, and so do I. We have it down so well now that we can pretty much cum at the same time, or close to it.
You missed out answering my question about what you won't do with your boyfriend that you will with your lover and why you wouldn't do those things. You talked of no boundaries which suggests specific acts or some form of kink.
