Study shows, Penis Size Does Matter, especially to women that have vaginal orgasms through penetration
Despite always hearing “size doesn’t matter,” this actually isn’t totally true. It may be true to women who cannot achieve orgasms through penetration (between 70 percent to 90 percent of women are unable to achieve orgasm with penetration alone) but penis length and size does matter to the rest of us that do orgasm through penetration.
Studies find that women who have frequent vaginal orgasms are more than likely to have an orgasm easier if the man’s penis is longer. For me specifically, it is the length that triggers my body’s orgasm during sex. The bottom of the vagina, also known as the posterior fornix, has nerve endings that are not attached to the clitoris and give an entire different sensation sexually. This is also known as the p-spot. And although it’s common to hear it’s the width that matters, that isn’t true for me. If it isn’t hitting the p-spot, it’s just stretching my walls and possibly ripping me. And that never feels good. And apparently, I am not alone, as women who tend to prefer penile-vaginal intercourse over other types of sex (oral) also say the same, researchers reported online in The Journal of Sexual Medicine.
But other researchers were less convinced.
“There’s such variability in preference,” said Barry Komisaruk, who researches female sexual response at Rutgers University. Women who orgasm through vaginal stimulation may indeed prefer longer penises, Komisaruk told LiveScience, but not everyone prefers to orgasm that way. (10 Odd Facts About the Female Body)
There is no doubt about that! For the first 20 years of my sexual life I could only orgasm through masturbation with my fingers on my clitoris, oral sex, or the use of a vibrator. All purely clitoris orgasms. It didn’t matter the width or length of the penis, my body was unable to achieve orgasms through sex. When that changed, and I became orgasmic through sex (various factors: age/sexual peak/comfort/and learning to pay attention to myself and stop making theatrics during sex a priority), I noticed that if my husband isn’t going all the way in, it is far less enjoyable. Depending on positions, such as him laying sideways, there is not as much penetration as positions like doggy style or missionary with my legs up. If his penis doesn’t hit the bottom and create that posterior fornix pressure, I cannot achieve an orgasm. When his penis is totally erect and bottoms out, it can instantly trigger orgasms. And most of the time it doesn’t stop until he orgasms or slows his pace and allows my body to recover. This bottom area is where the p-spot is located and creates a sensation I can’t really explain. For those women that have felt this, they know. It’s almost indescribable.
But let’s get back to these studies.
There is still scientific debate about whether vaginal and clitoral orgasms are different phenomena. Different nerves carry signals from the vagina and from the clitoris, Komisaruk said, and stimulation of each activates different brain regions. But some researchers argue that vaginal stimulation is simply activating a different, internal, section of the clitoris. Women report different sensations from vaginal and clitoral orgasms, Komisaruk said, but which one women prefer largely comes down to personal preference.
In some cases, female orgasm is even more complex. For example, Beverly Whipple, professor emerita at Rutgers University and one of the discoverers of the G spot, a sensitive area felt through the front wall of the vagina, has found that women with complete spinal cord injuries can sometimes experience orgasm, even though the nerves that carry sensation up the spinal cord from the pelvis have been severed. It’s likely that the sensory vagus nerve, which runs in the abdomen but bypasses the spinal cord, is recruited to carry signals to the brain in these cases, Whipple told LiveScience.
That’s actually pretty interesting. Being that a longer penis can push around the abdomen area much easier than a short penis, it would explain why depth matters! And it also explains why other research has found that abdominal exercises induce orgasms in some women, resulting in pleasurable spasms at the gym.
Some researchers holds a different view, pointing to studies finding that the ability to orgasm with vaginal stimulation alone is correlated with better psychological functioning, better relationship quality and greater sexual satisfaction.
“Earlier research with a large representative sample also found that women who are made aware in their youth that the vagina is a source of women’s orgasm are more likely to develop the capacity for vaginal orgasm. Therefore, those who deny these findings (and insist on maintaining the politically correct party line) are not doing women a favor, but might be injuring women’s health and sexual potential.”
Length isn’t the only variable with orgasms during sex, that’s for sure. As I stated earlier, I was unable to achieve orgasms sexually, regardless of length. It wasn’t until my 40s I was truly able to enjoy orgasms through sex alone and there were a lot of mental factors that played a part in it. But once all those mental factors are sorted out, size does matter!
So my friend and his girl have been continuously asking me to join them in a threesome after a night out at the bar. At first I didn’t think it would be a good idea but they kept asking and I finally said yes. We just set out the rules that I wouldn’t cum anywhere on or in my friend’s girl which I was completely fine with but everything else they said I can feel comfortable doing.
This is where the problem starts. I’m more of the dominant person in sex and I know his girl was digging that. I was kind of controlling her and telling her what to do next. The alpha. Also I don’t mean to say this in any cocky or weird way but I’m just the bigger guy there bein

You have to suck dick like you don’t have a care in the world. Lose yourself in how sexy you look with a dick in your mouth. Show him confidence. Show him you’re sexy because you say you’re sexy.
No matter what you think you look like, what does he think you look like? I assume if he is dating you, he thinks you are beautiful. If he goes out in public and holds you, is proud, and shows you off to the world, he adores you. When he watches you giving him a blow job, it doesn’t change, it just gets better. If he doesn’t treat you like his princess and show you off in public, then this is just a self esteem issue you have to deal with. Until you treat yourself like a beautiful person, no one else will either.
