I need bigger!

So I’ve been with my man for almost 3 years. I lost my virginity to him and we couldn’t get enough from each other. Sometimes we’ve had sex 9 times in one day. The past few months I feel like I’m super horny and when I put it on him he doesn’t give me enough. I never cum from penetration only and I constantly ask him to go faster and deeper even when he is as deep as possible. He’s 5/6 inches and it doesn’t feel small. I just feel like I need more for some reason.

I keep telling him that perhaps I should use toys but he doesn’t like that idea and He just tells me to finish the job after he’s cum and left the room or is laid next to me. Obviously that makes me feel uncomfortable so I never do and I never end up cumming. We live together so it’s rare that I get time alone to make myself cum as well.

My question is what do I do?! I love him so much but I’m so frustrated and horny ALL THE TIME. I need a release 🙄
