Only when he wants to

My boyfriend and I have been dating for 3 years, we have sex often enough to the point where I don’t ever have to ask (I’m usually down to do it anyway) and tbh he’s good , however I get urges too, but whenever I want to have sex it doesn’t happen and lately I haven’t been satisfied it always feels like a quicky which then makes me feel like shit like I’m just something to cum on. Whenever I bring it up to him he denies it and tries to hug me and kiss me which gets me a little more heated, like bitch don’t try to shut me up with that bullshit, in the end he acts like it isn’t true and I’m back to square one. I don’t know what to do I’m sexually frustrated !
