The foreskin should not tear during intercourse or at any other time. If this has occurred you should see a doctor.
Does partial removal of foreskin increases time of sexual intercourse for men?"
Yes, the males do, as do most male animals.
A membrane (a thin layer of tissue) called the hymen (also called a maidenhead) partly covers the vaginal opening. The act of intercourse tears/breaks this membrane. However, the membrane can be torn in other ways, so it isn't a certain sign a girl has had intercourse. That is, if a girl has intercourse the membrane will be torn, but the fact that it is torn does necessarily mean she has had intercourse.
During sexual stimulation your foreskin naturally tends to retract, you do not need a circumcision to have intercourse. It is mostly done for cultural or higienic purposes.
Yes, it may.
The foreskin is not removed during intercourse. The foreskin is a double layer of very sensitive skin that covers and thus protects the glans penis. In the area where it is against the glans penis it is covered with a fine layer of mucous membrane. The foreskin is designed to be able to be pulled back wards exposing the glans penis entirely and then come back to cover it again on its own accord with the aid of the frenulum the ridged band inside the end of it puckers it in such a way as to hold it in place over the head. When you have sex the foreskin is pushed back as a result of the friction of pushing it into the vagina and as the penis moves back and forth so does the foreskin making the movement more pleasurable and less forceful for both male and female.
The foreskin works in a number of ways to maximize the sensitivity of the penis and to maximize pleasure during oral sex. * The foreskin functions to protect the sensitive glans (head) of the penis, keeping it moist and protecting it from rubbing against clothing, which can slowly desensitize the glans. * The foreskin itself is also very sensitive and rich with nerve endings, making it very sensitive to stimulation. The inner foreskin and frenulum are the more sensitive parts of the foreskin. *The foreskin works to facilitate a natural sliding motion during sexual intercourse, oral sex, and masturbation. The foreskin slides up and down on the head of the penis, which not only stimulates the foreskin itself, but also provides additional stimulation to the head of the penis. The natural motion of the foreskin also allows masturbation without the use of additional lubrication. While oral sex is certainly pleasurable for both circumcised and uncircumcised men, the uncircumcised penis is fully equipped to receive the maximal stimulation provided by sexual intercourse, oral sex, and masturbation.
That would be very doubtful as most girls are unlikely to see a guy without one. most men throughout the world have a foreskin. and as one of the functions of the foreskin is to ease the need for lubrication as it slides back and forth during intercourse. make an easier entry and give nore sensation during intercourse the majority of girls that have experienced both tend to put their vote with the intact penis rather then the incomplete one.
something could have been torn during intercourse. Was there some pain after and or when going to the bathroom? If so, could be a small tear. Give it a day or so to heal. If not, could it have been your period starting?
Depends how bad it is. It needs treatment like a bandage. If its really bad. Then definitely seek medical help.
Possibly pulled back at the wrong place, and tore due to strain... Or dry skin/infection, or she was tight her self.. can be many things.
No. Once a woman's hymen, or "cherry", has been torn through intercourse it is very rare for it to regenerate.
