Hay! Im also a christian, but having sex before marraige.
My whole family is like, "we are going to wait till were marraide and its going to be perfect!"
but thats totally not true, god could make it perfect but you do have to do somethings yourself.
Pornos are so good sometimes but are very "ungodly" so it depends on how comitted you are.
To be perfectly honest... It takes a lot for us women to get excitted, I was with my boyfriend for 6months before having an orgasm.
Is your husband lazy? Make sure you have lots and lots of foreplay.
Dont worry about your husband for once and take control, do everything you want to do in bed because men are happy in bed no matter what.
Or you can just buy a vibrator
good luck!
.... Prayer would help as well, god can do anythign if you ask him.
