If taken correctly according the instructions, at the same time everyday.. the pill is over 99% effective. If there are absolutely no worries about STDs, then you will be just fine having sex without a condom and even ejaculating in her, that is IF she is perfect with taking those pills.

I've been on the pill for about 4 years.. I've never had any preg. scares. I'm far from perfect from taking these things too.. I'll miss a day here and there. And at the time of my relationship, my boyfriend and I would have sex and he would ejaculate in me half the time. Still, no worries at all. So the pill is extremely effective in preventing pregnancy..
