My sex drive vs. his

Lacey • 21 year old babe from Australia ;)
I'm 19 he's 22 been having sex for 2 of the 3 years we've been dating and in the beginning my sex drive was the same as his but now I am ok with sex 1-3 times a week but he wants it every morning and every night. This has put a huge damper on our relationship for the past year now. 
Any advice?
