Im a pretty good girl. Been married about all of my adult life and was a virgin when I married. I have of course never been with another man and hope that fate never touches my family.
But with all of that being said: even this geeky ol southern baptist country girl has a few things I reflect on and feel some shame about.
I feel very confident that if I feel this way - 90% of all adults do.
Be good to yourself - God has forgiven you and you cant do his work until you get over this - forgive yourself. We anger God when we are self consumed and not working for him. Then you can think about doing his work rather than the shame.
God bless you and good luck. Whatever it is will probably be funny in 5 yrs. Trust me.
