I'm speaking from a woman's point of view & one who also loves intimacy in every aspect.
First and foremost, you are correct it's natural for a man or a woman to masturbate and it can occur before intercourse or after intercourse. Intimacy consists of a variety of things or usual activities, especially when one has been married for a long period of time. It requires more interaction with one another to keep the fire lit so that one does not grow bored with their partner.
I see it this way... if your husband enjoys self masturbation why not join in with him because it's evident this is something that turns him on. Why give the pleasure to another TV/video chick when he'll be turned on just as much while watching you? We women tend to believe that there are things that are out of our element or character & that if we indulge just a little it'll degrade us. Honestly, I see that as a problem... we ask why our men/husband does the things they do (i.e. cheat, watch porn on TV or the web or even call the sex line for phone sex with an unidentified party). But what we fail to realize is we as women/wives have gotten so comfortable with our relationship that we don't need to do the things we used to do before marriage... and this is where majority of the women/wives fall short. You are WRONG!!! You have to learn to maintain your man/husband's interest when it comes to the great love of SEX. And this will involve trying new things and venturing outside of your normal activities... ROUTINE is BORING.
My belief is what you won't do another woman will do (and this applies to the men as well). Ladies every man wants a woman in the street & a freak in the bed, therefore, you have to learn to be his slut, bit**, who**, and his wife all in one.
They key is knowing & learning your man's cycle... you have to know when he wants Victoria (the wife) and Michelle, Kimberly, Angela, Anna, etc ( the many freaks on any given day). And it doesn't stop here because you can't give him sex in the same positions or places all the time because the idea is to keep him on his toes & guessing what's next. Role playing & dressing yourself helps to keep the flair growing in the relationship/marriage... find out or try blind folds, handcuffs, paddles, etc with one of the freaks of the week you'll pretend to be.
And when you are his wife the excitement doesn't stop there... change your look up sometime as well and how you get dress or undress in front of him. Strip tease him a little, walk around in sexy lingerie, etc. It's not hard to please a man if you know what you're doing, the secret is to eliminate the shy girl inside of you and learn to dominate him.
Cheating isn't the answer, how this turns out depends on on you.
I promise by adding some spice into the relationship/marriage your man is guaranteed to leave the porn alone. I can go on and on, but I think you’ve got the picture… Good Luck!
