Anal gone wrong?

Husband and I were doing the deed... quite spontaneously we decided to do anal. He wanted to finish in my vagina. So he did. Afterwards I went to rinse my body off of all the lube and sex. When I was cleaning my anus I noticed some.... yeah. Ya know... I’m not sure if it was just me doing Kegals to clean my vagina. That might’ve pushed some of that out or if I might’ve got poop on him. Since he double dipped. The Real question is what should I do? I’m scared to get a UTI or any infection. Since I’m high risk for it. Any suggestions? No judgement please!
