Alright, so me and my boyfriend had sex for the first time yesterday. It was my first time ever having sex, but I was confident about it. We used a condom and he is very safe about it. As well, during sex he does not have an orgasm and will pull out for my comfort of mind. He makes sure there are no holes in them and uses them how he is told. However, I have a few questions.
1) How protective is a condom?
2) As another precaution, I made sure that he ejaculated BEFORE we engaged in sex at all. This we did in the morning at about 8:00AM and had sex at around 3:30PM. What are the chances of pregnancy using this method as well as a condom and pulling out?
3) I am making sure I start going on the pill or the patch, but do not know much about either. Which is more recommended and why?

I know that I seem paranoid taking so many precautions, but I do not want to continue having sex until I have made sure of as many contraceptive ideas as possible.
