there is nothing to worry about the hymen has to be broken for sperm to enter the fallopian tube.

In one case there is a contact, in the other, there isn't. Well, at least that's what it looks like at a first glance - it seems that the "non-contact" forces such as electrical, magnetic or gravitational forces are actually mediated by the exchange of particles.
A spring force is a contact force not a non-contact force.
contact force:when two objects are in contact with each other it is called contact force.non-contact force:when two objects are not in contact with eachover
Magnetic force is a non-contact force.
It is a non-contact force - no contact is required for the force to act.
You actually don't have to penetrate at all, you just need pre-ejaculate or ejaculate to come in contact with the females vagina to get her pregnant.
A males ejaculatory fluids (Pre-ejaculate or ejaculate) must come in contact with your vagina for you to become pregnant.
To get a woman pregnant semen has to come in contact with the vagina. It is possible to ejaculate without an erection, did you ejaculate? And if so did the ejaculate come in contact with her vagina? Without an erection it would be difficult to deposit the semen deep within her vagina so it would be more difficult to get pregnant but I suppose if you ejaculated without an erection then took the ejaculate and pushed it into her vagina then it would be possible.
yes
no! to get pregnet she needs to have her periods>
You Should Keep contact with your ex-boyfriends so you guys dnt hate each other it's the rite thing to do
It is not possible to get pregnant from oral or anal sex. If the penis comes in contact with the vagina at any point, though, there is a risk. Particularly if the male ejaculates on or around your vagina. It is also (less) likely that you could get pregnant from pre-ejaculate ("pre-cum"). If you are concerned about pregnancy risks or think you may be pregnant, contact your doctor.

Yes, sperm are present in pre-ejaculatory fluid. Hence it is entirely possible for a woman to become pregnant even if the man does not actually ejaculate. If you want to avoid pregnancy, any contact between genitals (up to and including penetration) should only happen with protection.
First I will always say that unless you are abstinent, there is always a possibility of being pregnant. Yes, you can get pregnant. Common myths suggest that you cannot get pregnant while on your period, that is false information as well; although it is less likely it is still possible. You can also get pregnant from pre-ejaculate as you might not have thought because pre-ejaculate still contains sperm/semen. The pullout or withdraw method can still have sperm or semen that can come in contact with the vagina and get a female pregnant.
This is something I cannot answer. If you are old enough to produce sperm, then you have enough to get a girl pregnant. A male is capable of releasing small amounts to over a billion sperm when he ejaculates (http://www.livescience.com/mysteries/080606-llm-sperm.html). So, even if you don't ejaculate, but there is semen that comes in contact with your partner, she can become pregnant.
