love and sex both are a must

I'm not gonna sit here and say that I haven't forgone the nice guy just so I can have my heart broken by the bad asses I'm usually attracted to but this time it's different. I actually like the nice guy and want to be with him. We click and can talk and of course super sweet! But........ the sex is bad. He does know his way around going down but when I want to get more he is so small ........ I'm sorry a little size is needed. Is this the universe saying hey the bigger the jerk the bigger the dick and awesome sex and the nicer and greatest guy ever you have no sex life.  I kinda just get uncomfortable when we are alone now cause I don't want to walk away unsatisfied again. So now what do I do??????????
