After 25 yrs of marriage and 3 kids...my ex traded me in for a younger model. Its been over 4yrs since the divorce and I'm still torn up over it, dwell on it everyday. We used to have a very satisfying sex life, albeit slowed over time but satisfying nonetheless. My question is.... at times I would fill her up with air, every stroke was like inflating a balloon until some sideways action would deflate her. Does this happen to everyone, some, none? and what causes that to happen in the first place.
