Women on penis size

You need to only ask yourself one question do dildo or Vibrators came in 3 inch ..... ........NO cause why would they you wouldn't be able to feel 3 inches like putting a tampon in Loser

I have a big penis and my wife is happy with it. But my wife is a size queen, and likes to get her pussy stretched out and filled up full. We have a large dildo collection that I use on her. I have no problem with playing with them and like it as much as she does. But they don't make her orgasm, g-spot massages and clitoral stimulation are the trick to orgasms and ejaculation. Learn how to do these things on the internet. Its very easy to learn the techniques.

You need to have an honest talk with her. Is she really satisfied? Are you? How does failing to bring her to orgasm make you feel? Can you get her off going down on her?
You should find out what she wants, and help her get her needs met. If you have fantasies, tell her about them.
There is no sense in going through marriage without pleasuring each other or helping each other get what you need.
Of course, there are women who don't have very high sex drives; women enjoy the intimacy a great deal, there is much more to sex than penis size. Your whole relationship with her is important to her. It is entirely possible that she is being totally truthful with you and she is satisfied with you.
But are you satisfied? Why did you ask? Do you want something different in the bedroom? some guys want to watch their wives fucked by bigger dicked men. that is a thing. Some smaller dicked men want to be cuckolded, even sissified. Be honest with yourself, then broach the subject with her, if that is what you want.

Have you tried pleasuring her? Maybe it's not your dick, it's just the way you fuck.
