My boyfriend & I had sex twice tonight without a condom.

Before the first time, he peed & we used a condom for about 5 min then we took it off. He pulled out and told me to jack him off then he came on my stomach. He peed after.

Round two, no condom again lol

He pulled out, jacked him off then he came again in my stomach.

This isn't suppose to be a dumb question so don't judge me lmao, but what honestly are the chances I could get pregnant and should I get a plan b?
