boyfriend never wants to have sex?

So my boyfriend and I are going on two years and he never seems to care to have sex but like...once a month. I know he loves me (we plan on getting a house together soon and everything) but we never do it!
I gathered the courage to ask him why and he said it's more meaningful when it's spread out/sex isn't as important to him as "most guys" and so on-and he certainly seems to love it when we do do it.
Every girlfriend of mine seems to have sex almost daily! Is this abnormal or just rare...
I'm fine with it as long as it's not an excuse...it just doesn't seem like one but is way odd. >.<
