[QUOTE=darrensusername]hi.. umm this is my first time posting.. im new to sex i have only had it like 10times and i try making each time new and when me and my partner have sex we try different positions and i guess the topic is a little vague but i main question is .. why in some positions i tend to cum faster? for example when we do it doggy style for some reason it feels different and i feel the urge to cum faster than missionary.. i find this happening in many of the positions i try out.. any help?[/QUOTE]Try using a period in your sentences, so that we can actually figure out what you're trying to say. Using capital letters in their correct places is also a good thing.

You blow your load earlier than you want to because you are still excited to these new and wonderful positions. You're feeling new sensations and your body is responding by exploding in excitement.

All orgasms, male and female, are release of muscle tension, mostly in the lower abdomen but including the entire body. Some men are able to control the tension in some positions but not in others. For instance, in the traditional missionary position with the man supporting himself there is great tension in the arms. This causes some men to reach orgasm faster because they are so tense; it slows others down because so much energy is going into supporting themselves that there is little left to other parts of the body.

Each man is different in what makes him last longer or come more quickly.
