I want more pleasure from masturbating but can't get it.

I've been masturbating since I was 12, I am now 21. I've started out using my fingers, but only one then moved up to two as I got older. I would do it all the time, especially in the shower. It was out of habit, I never got any pleasure out of it. It wasn't until I was 19 I found out what rubbing my clit could do. it's all I've done since. Recently, I've been trying anal masturbation, and it's amazing! I want to be full all the time! But the process it takes to clean myself before anal is such a hassle so I've been trying vaginal instead hoping I'd get the same feeling as anal. I've used small things, my two fingers, razor handles, etc. but I feel nothing! I moved up to four fingers now and I still don't get the satisfaction, they're really short. So I tried using a faux banana with a condom on it (I've used it for anal). I slicked it up with lube and stuck it inside me, problem is, it goes in, fits perfectly, but it would go far AT ALL! it's barely the tip that will, and I'm eager for more! I fit my fingers in further and they are wider than the banana. My vagina started burning and now I have an uncomfortable feeling inside of me. What could be the problem? Please help!
