Is it possible?

Now before I️ say anything I️ don’t care if I️ get pregnant and I️ don’t plan on getting plan B. Anyways my boyfriend and I️ were having sex yesterday and he kept stopping because he said he didn’t want to cum yet. We were going at it again and I️ felt a little bit of burning (when he finishes in me it burns a little and I️ have gotten tested). He stopped again but pulled out when we went at it the third time. I️ also saw a lot of white creamy looking discharge on his junk but I️ didn’t know if any got in me.
