Sex drive - HELP

I really need help ladies. I don't know what it is but I have a low sex drive. At least compared to my man.

I'm 19 and he's 22.

I could have sex 2-4 times a month and be great.

He would rather have that in a week.

He admits he has a very high sex drive and with me having a low one it's hard to make both of us happy all the time.

He says it leaves him horny all the time but when he says things like this it makes me feel like a shitty girlfriend or I'm not adequate enough for him

Any suggestions?
