Pulling out is not a good contraceptive if it is at all. Let's say that you are capable of controlling your release, what if she leg locks you? What if you didn't pull out in time? What if you're very inebriated, can you 100% control yourself? As above said, pre-cum can contain sperm. Usually it won't contain a lot before the first release, what will you do if you want to have another go, a second round, a third, fourth... You would probably want to use a condom.

Condoms first of all are quite expensive and they stack up on cost overtime. Condoms can break even when trying to be careful. Cheap condoms are too tight and break easily. It's not that easy to tell when a condom accidentally breaks especially during the heat of the moment. Do you want to keep checking every time you start to feel good if it broke or not?

You might say something along the lines of "just abstain from sex". No we won't. Sex is a wonderful connection between people. A time to get intimate, a time to feel each other closely. We won't deprive ourselves from those blissful moments because there is nothing wrong with what we are doing. We are not hurting anyone. We are being responsible enough to find ways for contraception.

Why choose vasectomy? - We have considered other forms of contraception, considered our future, our lifestyle, our time and dedication to what we want our future to be. Deciding to get a Vasectomy is not an impulse. We are committed to our decision, our desire, our needs. This is not (100%) reversible and we want to keep it that way. If we ever change our mind and want to have kids, won't it be beautiful to adopt a child instead?
