I am frustrated with me and my boyfriend´s sex. And it´s making me feel bad

As long as you are open and honest with him about your desires then that helps. He should be open to trying things unless they're illegal or really, really immoral. If he's at least willing to try new things that helps. But if he's totally against even trying, that's a bad sign. Relationships take stepping out of comfort zones from time to time, including sex. That doesn't mean fucking on a park bench just for the spice of it but, I'm sure you get the idea. If he tries things and gives it enough effort/attempts and just simply doesn't like it, then move on to something else new. I think people are into a whole plethora of kinky/fetish-type things, they just haven't tried them yet so they don't know if they'd like it.
