Anal...

My boyfriend really loves doing anal, and I don't mind it either but I'd rather have regular sex tbh. But I let him do anal because it's a nice little treat for him. And I let him come inside of me if we do it this way because no harm done, right? But I always get nervous that some of it will drip out of there and into my vagina. I try my best to clean it all out after but I still worry. I'm really good at worrying lol. I'm on bc, so it shouldn't even matter if it does but 😓
