tmi alert but need advice

Danielle • Dog mom🐾 mother of Irish twins 🌈 👦 🦄 👧

this is tmi but here goes...so the night my husband and I were going to do anal I used an enema as usual, and after I was cleaned out I stuck a finger up there to loosen it up. when I did so I feel like this lump.like it didn't hurt or anything like that. I was wondering if that's a normal thing like some kind of gland?
