no
Well, friction occurs. It could be static, fluid, sliding, or even rolling friction!
Yes. Even objects whose density is greater then the fluid's.
when two fluids are combined surface tension forms at the points where they are in contact. fluid a will push out on fluid b equally in all directions, and fluid b will push inwards on fluid a equally in all directions. because pressure will be even at all points, the resultant shape will have an even distance from the center at all points IE a sphere. cause hemiphere is round
The density of a fluid will increase according to applied pressure. Even water can be compressed so much that it eventually turns into a metallic substance. Compressed fluids will however not remain in this state when pressure is released.
Fluid that it attracted to a nearby surface and remains attached even when the surface curves away from the initial flow direction.
Precm, I assume you mean precum? This is a measurement of non ejaculated seminal fluid. It is usually a very small drop. The fluid contains a lower sperm concentration than ejaculated semen. Theories suggest it may serve as either a cleansing fluid or even natural lubricant.
There is no risk of fertilization, since men do not have an uterus. You partner cannot get pregnant even if you ejaculated inside him wherever the place.
You can "pre-ejaculte" even if you have never ejaculated before and get a girl prgnant. There is almost always sperm in pre-ejaculate.
No, even if a male ejaculate only the prostate's secretion, the result will not be on liquid form.
If you are just in the room or bed with the man when he ejaculates the possibility of pregnancy is 0%. The only way that a pregnancy would be possible would be if he ejaculated on your vagina. Even then the likelihood is exceedingly low.
Yes, even a little still means there's sperm in it that can fertilize your eggs.
The Parking Brake could be set (even slightly)
The suggestion that seminal fluid might travel through the water is practically impossible, even more so at elevated temperatures (which would rapidly deteriorate any sperm). Preejaculatory fluid will usually only contain minute amounts of sperm. However, anytime an uncovered penis is in proximity to the vagina of a female (especially an uncovered one), there is the potential for sperm to reach the vaginal lining. Underwater sex is no safer than anywhere else. But any significant chance would require direct contact between the male and female genitals, because of the deteriorating affect of heated water.
yes...yes a girl can the sperm can b ejaculated enough to get her pregnant even with out penetration to the vagina
Yes. There is also preejaculate and other fluids.
The calorie content of semen is negligible, and consumption of it, even daily, would not be noticeable in one's physique. Since you ejaculated it, you do not gain by eating it, you "break even."
Sperm can be viable for a few days inside a woman's body, even up to five days.
