Liquid Coming Out Of My Anus😬

So me and my boyfriend wanted to do anal again for the 2nd time. The last time we did it was like a day ago. But today we did it and I after we was done I went to go use the restroom and a yellow/cleanish liquid came out (I thought I had to poop) My boyfriend did use some type of gel on his penis so it could slide right in when we had sex. But idk what this is and he did cum in my anus so. I really don’t know what’s goin on☹️ Need help!
