Ive come to believe the vagina evolved to work as a trapdoor/pully system during sexual penetration using the clitoral bulbs located on either side of the vaginal opening and connected directly to the clitoris, combined with the labia being tugged into the opening which pulls the hood down allowing indirect stimulation of the clitoris, the pubic skin/flesh is also slightly firmer than other regions of the body. The skenes gland/gspot also provides sensation. Optimally thrusting to increase downward tug of the clitoris during sex would appear worthwhile to say the least
-
I'll mention that foreskin also known as the clitoral hood may be a very desireable trait which can increase surface contact with the clitoris during downward motion

If this was so men who had not been circumcised should be more attractive to women but I do not believe this is so.
-
A close friend of mine who is gay, told me that he prefers circumcised men, because (to quote his words), "you see it more". I don't know whether this is to be believed.

I originally titled this thread 'female sexual mechanics', there was no question

You need to keep track of the bigger picture. The natural purpose of sex is to make babies. This is how genes are blended and transferred forward into time. The pleasure of sex is secondary to the prime directive. The pleasure acts like a carrot on the string that leads the horse to water. There is a tendency to place the pleasure cart before the reproduction horse and then reverse engineer the function of body parts based on the cart.
An analogy is, eating is designed to feed the body, nutrients and energy. Food tastes good, because this is the carrot on the string used so we will eat and the body can gain nutrients. The taste of food is the cart and nutrition is the horse. If you eat only for pleasure, this can cause problems such as obesity; cart leads the horse and we lose instinct. If we could make saw dust taste like a prime porterhouse steak and like cherry cheese cake, many people would place the cart first, eat for pleasure, but starve and have nutrient deficiencies. If we made a bland food pellet that was boring to eat, we can still feed the body, be healthy and live.
Sex can be different, whether we have a new lover or whether we have a lover that has been around for some time. With the former, you don't need gimmicks. The instinctive drive/horse for reproduction does it all, allowing the cart to be pulled around and amplified. With the latter, gimmicks become more important, became the cart is placed before the horse; prime rib sawdust. One may be still hungry so they try ice cream cake sawdust, but even that leaves you full but sluggish.
Since reproduction is the prime directive, the vagina is design with this in mind. Eggs needs a certain temperature and access to future resources, which places them deep inside the woman. Access has to be regulated to prevent disease entry, but still allow access for fertilization. There are provisions for that. If I am not mistaken, human females are the only female with a clitoris. This is connected to the cart of pleasure, allowing sex out of season; natural selection.

In all conscious organisms pleasure is the primary incentive, most animals are incapable of comprehending reproduction or predicting the future on a level that would motivate them to have enough sex to sustain their population. Nutrient deficiency ensures we stay hungry, nutrients are responsible for taste, animals become desensitized to improper nutrients
Most animals have clitorises, in hyenas the entire vagina is one big clitoris

While potentially considered less aesthetic(which I disagree with), or harder to clean before soap and showers were invented, male foreskin which is analogous to the female clitoral hood evolved to protect the penis head from injury(warning: partial severance) while also providing more sensation, girth, and better thrusting for both male and female during sex, the foreskin reduces wear and tear which delays the onset of erectile dysfunction. The female foreskin aka clitoral hood increases surface contact with the clitoris as the penis penetrates the vagina pushing the clitoral bulbs outward forcing the clitoris, clitoral hood and labia to tug downward toward the hole proportionate to the girth of the penis. Mutilation of this vital organ is especially tragic in western society where men are often less than ideally driven to become angry masturbators or “w***ers” as referred to in the great state of england, else face wasting their orgasms during sleep every 1-2 weeks

While most people have heard hand size, foot size and overall body proportions correlate with penis size, the best indicator may be head shape
Since head shape partially indicates the shape your head squeezed through at birth, head shape can indicate the shape of your mothers vagina which is analogous to the shape of the penis
Head wideness can indicate vaginal wideness which indicates c-v distance (distance from clit to vaginal opening), wideness is analogous to penis girth and c-v distance analogous to penis length both proportionate to head size
C-V distance is the primary factor responsible for penetrative female stimulation, followed by trapdoor mechanics which relies on tissue elasticity which affects healthy pregnancy
Assuming tighter females with shorter c-v distance can enjoy penetration more, smaller head size can indicate straighter females but decreased mental capacity and less-hung males, bigger head size can indicate smarter males with bigger penises but potentially less-compatible females
Optimally males should seek females with smaller well rounded heads or the inverse of their own head shape, females should seek males with larger well rounded heads or the inverse of their head shape
Since C-V distance matters more than trapdoor mechanics, slightly wider heads are a better sexual bias than thinner heads
Aesthetic and functionality including brain region affecting spatial, sensory, and balance are also relevant, wider heads appearing slightly more cartoon but thinner heads leading to decreased sexual compatibility
If you like lots of sex go for wider headed partners which may be an aesthetically counter intuitive tradeoff for some, keep in mind thinner headed people would tend to have stronger orgasms but less sexual compatibility between male/female
Opposites need to find a way to attract eachother in order to keep opposites attracting, racial (melanin) "opposites" rely on local climate, social environment, and other functional-tradeoffs determining the local-optimal, since racial mixing decreases DNA inflation which increases cellular density and elasticity mixed race females on average may have very slightly more clitoral motion or tug during penetration though C-V distance matters most
Erectile tissue firmness is another factor, heterosis likely improves the effectiveness of all the different tissues but still relying heavily on source genetics and only improving small edges
Combining facial features like sharpness and roundness may indicate or increase clitoral trapdoor mechanics
Foreskin may be the most important part for clitoral mechanics, cutting male foreskin may accelerate the evolution of desireable traits including intelligence which motivates intercontinental colonization/global communication and increases genetic mixing, female foreskin is more important than male foreskin but now that we understand physics and electronics i recommend decreasing the use of ancient evolutionary manipulation technology

Collagen promotes skin elasticity which can only be sufficiently consumed on high meat diets, veganism is creating less elastic females which may improve sex for some females but during pregnancy and puberty a diet high in collagen is necessary to minimize damage

In short: penetration causes proportionate clitoral displacement
Its a pleasure trap, lever, levy, levitate, double wish/helix
Double trap from above and below flowing into the vagina
