Is it strange to expect that a partner of almost 2 years be able to give me an orgasm?

I have asked my partner of almost 2 years if he ever thinks he will be able to give me an orgasm, he has been unable to do so in the bedroom in nearly the 2 years we have been together (and yes I have orgasmed before, I am capable of them). He claims that he is better at giving women orgasms with his mouth than with his \*ahem\* but that he just isn’t good at either and isn’t sure if he’ll ever be able to.<br><br>He is the first partner I’ve ever had that has been unable to do so and our sex is rather unfulfilling for me since he is unable to give me an orgasm (and he doesn’t care if he gives me one or not). <br><br>TL;DR: Is it reasonable to expect a long term partner to be capable of giving me an orgasm?
