First time Anal sex😅

So i just had anal sex and boy was it good. Me and my man did it in the shower, and i thought i was gonna hurt because we didn’t it without lube but it actually didn’t hurt as much as i thought it would to my surprise it was actually really really good, but does anyone feel like their going to poop? 😂 Cause i kept thinking that and thank god i didn’t, also would it be bad if my man put his dick in me after we did anal ? Big thanks if you answer 😅
