So, do you mean ‘going down’ on her or are you sucking a cock? I don’t think giving head is used for cunnilingus, is it? Maybe it’s just me… but searching ‘giving head’ on Tumblr says it’s about cocks. Anyway.. back to your question!
As for getting addicted, there’s definitely an element of that. Hubby used to go down on me semi-regularly before we got into all this but when he’s caged and denied it’s like flipping a switch and he’s offering more than I even accept a lot of the time, it’s fab!
