I'm on birth control, Nuvaring to be exact. I've been on it for three or four months now and my current ring had been in for two weeks. I put it in the same day I took the other out after it had been in for three weeks. I'm only twenty so me and my boyfriend use condoms every time as well to be extra safe but yesterday we didn't use one and I for whatever reason convinced him to cum inside me instead of stopping because we were enjoying ourselves.
