Robert M said: We use them every time we have sex. My wife has only had an orgasm with a cock a few times. Her clit is really small I don't know if that's the problem or not. She likes a large penis style vibrator inside and a wand type vibrator on her clit. I make sure she gets off first. I actually like going in second the big cock style vibrator and all the lube has her very slick and loose it feels really great. I figure whatever works. By the way she said she had a couple of "very large cocks" before we married and had no luck with them either.
My wife is the same, her last boyfriend before we got together had a massive girthy cock so she really enjoys the stretch. She uses all manner of huge dildos to get off and I love the feeling of siding in right after she's been stretched out, super wet and sloppy, the best.
