No!!
No.
no, She will not be pregnant but never actually have sex doing nothing but touching with a penis a lady feels more special if you put your dick inside her
Not very likely at all, but if you are worried have her take a pregnancy test
to get pregnant you have to have sexual intercourse, his penis has to enter your vagina for you to get pregnant.
The size of the penis has nothing to do with your ability to get someone pregnant. Its your sperm. So yes you can get a girl pregnant with a 4.5 in penis.
Maybe. First I hope your penis didn't touch her uterus, that would be painful. No one was using birth control - condom, birth control pill, patch, shot, implant....Your penis touched or was in her vagina? If you ejaculated (orgasm = semen & sperm) while your penis was touching her vagina (the man's part in making a baby - also called baby batter).If she was ovulating (had a mature egg) - ready for making a baby (the lady's part in baby making).All these things had to happen for her to get pregnant. No semen, no egg, yes birth control - means no baby.
I'm not completely sure of your explanation of the boys underwear. Was his penis inside the underwear? Or was his penis out through the opening? If a boy has his penis popped out thru the fly in his underwear, and his penis is in the area of, or in her vagina and he has an orgasm or he has the pre ejaculate fluid that comes in contact with her vagina. Yes, she could get pregnant. If he has his penis inside his underwear up against her vaginal area she might or might not get any sperm close enough to get her pregnant. Unless they have started making underwear for him out of latex (like in a condom!!) cotton has never been considered a good method of birth control.
You really can't get pregnant from pre-ejaculation, there is like a 1 to 100 ratio of it happening. I guess the only way you could get pregnant from that was if he had already finished outside of you and had gotten semen on his fingers and then fingered you. Even then, there's a very small chance you could get pregnant.
No
yes. unfortunately there is a chance. a small chance but a chance none the less
no
Tell him you are uncomfortable with that.
