Overcoming shyness

So me and my boyfriend have been together for over 9 months now and it's been great. When we first started dating, the sex was great and fun, frequent, and hot. now it's kinda boring​? And has also turned into a very rare occurrence. He's the only one who ever actually cums and he receives blow jobs whenever he wants. I just don't know how to tell my boyfriend what my needs are without sounding too needy or like I'm complaining. Plus there are some things I'd like him to do to me that I'm way too timid to voice.

Any tips?
