--How did it happen? Well... we've been flirting too much for the last few days and we agreed on having sex, nothing to end up in a serious relationship since we're both kinda heartbroken.--
Anyways, the thing is we were using a condom. Durex Intense Sensation.
and all of the sudden, he pulls out to spit to have a little more lubrication and he notices that it felt too direct. When we turn on the lights, the condom was broken.
Few facts:
We changed positions about a minute before and the condom was fine (I know because I took a look and licked.
It wasn't ripped... it was weird... like... the whole tip of the condom was eaten off :s
Example:

He doesn't shows lots of pre-c** when he is being stimulated. It's quite dry during stimulations (hand, oral or sex)(only counting him fluids)
This was the day after my period finished.
This was in my 2nd day of birth control (I know it doesn't covers for the first month or two)
We immediately stopped and got rid of the condom.
Is there a high chance?
