im 17, and so is my girlfriend. We had sex for the first time about a week ago and were both freaking out because shes supposed to get her period anyday now. I used a condom and all that, I made sure that I wouldnt get her pregnant. I didnt ejaculate, but some of my fluids lubed up the inside and it kind of half slipped off (more of my penis bunching up [uncircumcised skin, fully erect]) Is it possible that she could get pregnant off of this? If so, please tell me that its almost ungodly impossible. Im freaking out.
Do a search on wiki under Pre-ejaculate.
Click on reference  and this comes up,
"This study was designed to establish whether motile spermatozoa are released with pre-ejaculatory fluid and whether this fluid therefore poses a risk for unintended pregnancy. Forty samples of pre-ejaculatory fluid were examined from 27 volunteer men. Samples were obtained by masturbation and by touching the end of the penis with a Petri dish prior to ejaculation. Eleven of the 27 subjects (41%) produced pre-ejaculatory samples that contained spermatozoa and in 10 of these cases (37%), a reasonable proportion of the sperm was motile. The volunteers produced on up to five separate occasions and sperms were found in either all or none of their pre-ejaculatory samples. Hence, condoms should continue to be used from the first moment of genital contact, although it may be that some men, less likely to leak spermatozoa in their pre-ejaculatory fluid, are able to practice coitus interruptus more successfully than others".
If you have access to the actual research paper as well as the other two scientific studies, you will see that the researchers goes on to describe the sperm that they found to be LESS THAN THAT OF AN INFERTILE man. And further more, the sperm showed very little forwards motion. For all practical purposes, they were dead.
A man ejacu;lating less than 40 millionnormal motile and healyhy sperm are officially infertile. It is unreasonable to base a whole life philosophy and outlook on less than a million half dead sperm with very little forwards motion.
The source of sperm in pre-ejaculate fluid is not because there are sperm in pre-ejaculate fluid. It is left over sperm from a previous ejaculation that is left over in the urethra. The longer ago that was, the more dead these sperm are. A urination after a previous ejaculation will also clean the urethra and kill the left over sperm. The few hundred left over after that cannot find their way anywhere.
Pre-ejaculate is dangerous for other reasons. It is normally a sign that the couple is engaging in unprotected sex. With many men not being able to fully control ejaculation, this is indeed a very dangerous situation over which the woman have no control. And she will end up with the mess.
Perfect use of the withdrawal method approach the failure rate of condoms, around 3% to 5%. This shows that education around pre-ejaculate is totally misplaced. It is not the pre-ejaculate that is dangerous. It is the fact that the couple is having unprotected sex. They are often very young and the male partner have very little control over his ejaculation in his early and mid teen years.
If a condom slips, the chances are also very good that the few drops of pre-ejaculate in the tip will just stay right there and not leak out. Even when a condom breaks, the penis head will go through the side of the condon and the tip will stay intact. After ejaculation this changes as the semen will very likely be all over the penis head and leak out.
Added to all this is the fact that a woman needs to be in her fertile week, and that only one in three women with a full ejaculation right in their period will end up pregnant. So the chances are, for all practical purposes as close to zero as it can get that she can be pregnant.
Thank you everyone on here. My girlfriend got her period earlier this morning. Shes not pregnant. Thanks to everyone on here that answered, you helped us both and helped keep us calm instead of flipping out. I just hope if I ever come back I get a more immediate response. hank you all <3
