Minor medical issues are naturally quite common, and of course, some may be slightly embarassing to mention.
With that in mind, you must realize that Dominatrixes deal with the human body all day long – there’s not much we haven’t seen and a true professional won’t make you feel ashamed for things that are beyond your control.
Just be upfront and honest on the phone about any physical conditions you may have so your Mistress can prepare appropriately and decide if she is comfortable working around them. No need to be bashful darling!
