I have days that I just can't explain. I will awake and have nothing but anal thoughts all day. I get an overwhelming 'need' to play with my own ass and this will lead to fingers, toys, plugs all day. The day usually ends with my wife pumping my ass with a big dildo while I jerk off. I have explosive orgasms when this happens. This doesn't happen always, in fact it may only happen once a month. Other days, being anally penetrated is no big deal.
I am not complaining but I have a couple of questions. Does this happen to anyone else? Any thoughts on why this happens to me occasionally? The orgasms are so intense that I'd like it to happen daily!
