My tiny 3 inch dick

My penis is only 3 inches long erect and just a bit over 3 inches in girth. My wife says she can barely feel it in her pussy when I fuck her. Because it’s so small it pops out of her pussy when we fuck. Mosy of the time I use a big dildo on her so she can get some pleasure. She just gives me blowjobs instead if sex so I can get off.
