pre-ejaculate

Human Reproduction: A Seafarer's Guide

How a pregnancy happens is a lot more complicated and a whole lot more interesting than just a sperm cell and an egg cell running into each other. Here's our map to the way there...or not.

How could she become pregnant when I withdraw perfectly?

Sam
asks:
My girl friend says shes not had a period for 4 weeks now. She's been pregnant once before and says apart from when she was pregnant then her periods are regular. We have had unprotected sex for about 5 weeks but she climaxes before I ejaculate witch means I never ejaculated inside her (to be on the safe side, soon as we didn't have contraception)....

A cornucopia of "Can I get pregnant if...?"

asks:
Does precum contain enough sperm to get you pregnant if you have sex when its present? Also, if the guy pulls out and the cum gets all over your vagina and the a few minutes later he re-enters you, is that a pregnancy risk? My friends have told me that it's impossible, but I don't know. I'm scared, please help!...

Hi I'm a 17 year old girl and I've been sexually active with my boyfriend for a few months. We always use condoms. But recently we have been trying this new thing where I sit on him, facing him (naked obviously) and his penis is straight up and we just kinda rub up and down for a little bit....

So this all started a month ago, I had been on my period for five days and I had sex with my boyfriend during my period. Around four days later we had sex again. Then we had it once more a week after. He usually goes in me for like 15-30 seconds without a condom, and then he puts a condom on....

My boyfriend doesn't get pre-cum!

Love11
asks:
Is it possible that some boys just don't pre-ejaculate. I don't believe that my boyfriend ever does. I have checked multiple times to see if there is ever anything on the tip of his penis after he gets an erection and there is never anything there. Also, does pre-ejaculate always contain sperm?...

Pre-ejaculate, could I be pregnant?

If you don't know that your partner pre-came and you were having sex...but then 2 weeks later you didn't have your period could that be that I'm pregnant or could it be other things??...

Manual sex + pre-ejaculate = real pregnancy risk?

Lucy
asks:
I'm 17 and my boyfriend (16) and I have been dating for 2 years. We have decided to not have intercourse, but we do have manual sex sometimes. The last time we fooled around was about 2 1/2 to 3 weeks ago. I had my period last week, and it was on time, but only red blood for 2 days; then it was pinkish brownish stuff. Today and yesterday I've been peeing nonstop....

Is intercourse a pregnancy risk if he's not completely erect?

Lauren
asks:
About 3 weeks ago my boyfriend and I were messing around and wanted to have sex but he wasn't fully erect. He did however enter me and proceed to have sex. We did not use a condom. Three days later I had sex with him and used a condom. I've been stressed out since the incident and my period has not arrived. It usually comes every 2 weeks and 5 days and today is the sixth day....
