Urge Of pooping while having Vaginal Intercourse

L

So me and my husband when we had sex in position of Cow girl I had that urge that I’m gonna poop while I didn’t want too after I stop

We did this position before last time we met which is few 3 months ago and I didn’t have the same feeling please help !!

I’m newly married and I have zero experience in sex as I was virgin 🙈
