See my gallery pics. My wife keeps me shaved for that exact reason, she says she can't see it otherwise. Small penis isn't a problem, fits my hand perfectly while I'm licking her to orgasm. Improve your tongue skills so she keeps you around.
It looks like a cock, just smaller. She's right to cut you off as she's gonna get no benefit from fucking that tiny thing, She actually would like to feel a cock inside her filling her pussy, not just poking at the entrance.
