Sex Life Blues

Okay ladies...
I'm in such a funk here lately. I feel like I just need to vent & know that someone out there does not feel like I am crazy. 
My SO & me have been together a little over 5 years now. We are both 22 & live together. 
The last few months our sex life has sucked. Okay, if I'm being honest I've been complaining about this for about 6 months or longer 🙄
But my SO never wants to have sex, like ever. He's not cheating, I know that, but when we first got together up until the first year & half we were together, we had sex ALL THE TIME. Now, it's a constant fight when we talk about it. 
He says he does not have as high of a sex drive as I do & it's not fair to portray men as always wanting sex or being horny because it's not true, 
In my defense he use to have sex with me more & every one of my friends have sex 2-3 times a week & im lucky to get it once. 
It's really starting to take a toll on me. I feel like he's not attracted to me or that I have something wrong with me. I've tried buying sexy outfits & toys. I wore the outfit twice & we had sex, but he never asks me to put it on & after using the toys 3 times he never gets them back out. 
I feel like I've tried... I've expressed how I feel, tried to make it more fun, & it gets me no where. He says he's going to try to be more active in the bedroom, but since our talk almost 3 weeks ago we might have had sex 3 times. I won't even count the last time because he got off in under 2 minutes 🙃
I'm just so downhearted because although I know sex isn't the main part of a relationship, you can sure feel when it is lacking though. 
What else can I do? Do you think this is actually normal or is it just me?
