Well, it's still possible you simply have a high libido, but yes, I agree that 4 hours is perhaps a little excessive. lol The range makes it a little difficult...I think if it were one time for maybe 1 hour, you'd be fine, the 2-4 seems a little much. A therapist should be able to diagnose why you do this and help you cut down (though not out...there's nothing wrong with the act itself ).

Still, there's not any physical health effects that I think you need to worry about (but then again, I am a guy, so I would defer to the advice of one of our female posters there), so please don't let that stress you additionally. It won't affect your innocence, and I don't think it will alter your husband's perception of you one bit.
