ps -- Good for you to know that porn is designed to be mediagenic, and not lessons in sexual practice. Too many people don't know this.
I am sorry, the only medicine that I have ever heard that has an effect is the kind of medicine they use to numb a baby's gums during teething, and that would not only numb your organ but also numb her mouth, the poor girl.
My suggestion is twofold. One is, give of yourself to her not only sexually. Sometimes when someone has had a long, tiring routine during the day, a husband asking for sex at night (and feeling it is his reward to her) is just another exhausting idea, and this is true no matter how much she enjoys sex with you. Some nights a tired person just wants to sleep. Rubbing her back (without the expectation it will turn into sex) is a very loving thing to do on such nights. Second is to give her vaginal sex on many nights without having oral sex to you be the prelude. That way, you will know she can be satisfied at least on those nights when you are not expending all of your excitement before she gets fulfilled.
Go online and look for "breathing techniques to delay male orgasm," or "methods to delay male orgasm." Sorry my advice is not more helpful but this is all I can think of.
Thanks Annie for your kind opinion! The good thing about me and my wife is, we have never been indulged in sexual activities before. This is our first hand experience with each other. And Yes! You got it right!. We both take sex as a thing out of the world... We think about it the whole day, we plan new ways to please each other and we think we are innovative because we never copy any porn content. We do what we feel like to... The first night I released even before penetration, but she didn't feel it... In second attempt, I could stand for just a couple of seconds... For her, it was the peak... She knows what I tell her.... My state is her standard. So I am very much lucky!!! The reason I want to extend timing is, I really want to prolong the love making scene... I feel that the best pay out to my wife's all day long tiring routine is to give her the whole of my time in bed and satisfy her to the best of mine. Secondly, I have started enjoying sex after being introduced to it... So, I want the time to be increased... You seem to be an experienced person. Would you be able to suggest me some mild acting medicine which without any harm, could prolong my time quickly....???? I'll be really grateful to you.... Waiting for your response...
You are on a forum that is answered by lay people and not usually by doctors. If you want expert assistance, MedHelp has doctor-answered forums that charge a small fee.
That said, if you only have this problem with oral sex, not with vaginal sex, you have only a relatively small problem (which incidentally will probably be eased by the passage of time. Young men get aroused more quickly and have orgasms more quickly than men in their middle years or later, especially if the sex act is one they find particularly erotic, but over time they will get used to the eroticism of the act and will not be on such a hair trigger.) If waiting to get more inured to the action is not good enough, there are also methods of breathing and distracting yourself that are designed to slow one's orgasm. You would be able to find these online.
Speaking as a woman, I would say that although you think your wife is being kind to refrain from complaint about the speed with which you come to a climax when she gives you oral sex, she might not find it as disappointing as you think. (Unless, of course, she thinks you will start with oral sex and then move to vaginal sex, and you have taken the latter option away by having an orgasm. But that can be solved by starting with vaginal sex at other times.) The reason I don't think she feels disappointed in particular is that oral sex is not erotic for the person giving it, or at least not nearly as erotic. The only satisfaction to be had in this action, for her, is the satisfaction that comes from making your beloved happy. That can be very nice, but I have really never heard a woman complain that her husband does not last long enough when he is in her mouth.
