So my boyfriend and I had unprotected sex and he pulled out to take a break so he wouldn't cum, but he ended up cumming right when he pulled out. He cleaned it up and claimed that he didn't cum inside at all, just right outside of it. I have been on birth control for almost a year, but he still really wants me to take plan b. I think I'm fine, and it didn't get inside of me, but should I take it just in case?
