Withdrawal as a contraception?

[Jornot]

I'm still 18, and have a rather irregular sexual frequency with my current girlfriend. It can vary but lets say once to twice a month due to certain circumstances. As it probably happens to all partners, no condom in sight happens, and my girlfriend doesnt take the pill, have an implant, wear a cap, etc. We have been totally unprotected a small number of times. I've heard of pre-ejeculation but didn't know until recently that it could happen a long time before actually ejeculating. How worried should I be about this? We had sex yesterday unprotected and i withdraw well before my orgasm (assuming im fertile, everything else seems to work, and same for her) and I'm rather worried that a pre-ejeculation could cause a conception! It hasn't so far but it only has to happen once...Is it a myth? Or something to actually take very seriously?

you shoudl be worried. whenever you have unprotected sex you should be worried. stds...pregnancy...next time use condoms and have your girlfriend use birth control

It's too late! Thats why i was asking how worried i should be...apparently very

[Kim1989]

if pregnancy is "no suitable for you at the momemnt" then USE BIRTH CONTROL

pulling out and precum are GREAT ways TO get pregnant.

I would like to emphasize on the fact that I am 18 and have ambitions, and my girlfriend is 17 with high ambitions also, and a pregnancy is not suitable for us at the moment!
