Yeah, if you said your husband didn't masturbate regularly, then I'd believe that his sex drive is actually lower than yours. But the fact is that he does masturbate regularly, which mean he probably *does* have a sex drive equivalent to yours, if not higher... so there is something else going on. Have you talked about how this makes you feel? (I don't mean arguing about it, which you say happens once a month... I mean actually communicating your needs and finding out what his are.)
I find masturbation to be a good indicator of sex drive in general, at least as a baseline... I'm in a long-distance relationship, so my bf and I take care of our own needs during the week and tell each other about it (it helps to know how horny we are each feeling), and then bang each other silly (on a good weekend)

for two days. I suppose it will all even out once we actually live together.
