Not to make excuses for someone who is a shitty fuck BUT . . .
It could be that the two of you aren't compatible . . . yet
For instance, one of my girlfriends could not stand having fingers inserted in her, only rubbing on the outside. But my next girlfriend only liked having fingers inserted in her, no rubbing on the outside. Had I only had a one night stand with my second girlfriend, she would have thought that I sucked in bed, but after we were together for a while, she communicated it to me and then things were great.
Another example, some girls can't stand a guy thrusting deep, but other girls only get pleasure out of it if the guy is drilling holes in her. If you liked it deep, but you slept with a guy whose last girl liked it shallow, you might think he sucked in bed,when in reality he just doesn't know what you like.
by telling someone your likes and dislikes during sex, YOU can make THEM better in bed.
But, some people just suck no matter what.
