I am always looking for ways to make sex better for my wife. She worries more than I about PIV not working for her and doesn't want to suggest anything that will make me feel deficient. She only climaxes when I go down on her or when I rub her clit with the head of my cock. Penitration does nothing for her and she has always tried to be tight by trying to keep dry and having me try to penetrate before she is really ready. I think that she worries that she is too big. I know that I'm not going to get any bigger and she isn't going to get smaller so if you were married to a guy who has a dick like a thumb tack but without the head, short and skinny 4 inches long and less than 4 inches around maybe 1 inch across, on a very good day, which of the following might you like to try for more variety?

We have never been able to perfect the position to a point where my cock can stay in for more than one or two thrusts. That has always bothered me because I read that doggy style gives deeper penetration but it hasn't worked for us yet. But as they say, "if at first you don't succeed, try, try, again."
