I was actually thinking about asking a similar question. I remember a thread here on elite a ways back where some of the brothas were singing the praises of digital stimulation...saying it was amazing, etc.
So my question is....for those of you who are into this, how do you let your girl know that it is OK to do this? I mean, what if your rectum isn't clean? I know this may seem naive but I have never even thought to do such a thing. I have no issue with the whole licking thing, but that is external, y'know what I mean? And how does she get her finger in there? What type of lubrication? Saliva? KY? What?
