For me personally, it's not as simplistic as a linear and consistent high or low. I have to have some level of emotional attachment to the person before I'll get any sort of sexual urges, but towards said person, my drive will be very high. However, my sex drive, independent of a particular person or context, is probably pretty low to average.
I'd maybe put ISTJ and ESTJ below INTP but I think INTP on average is near the bottom. Of course there is still some variation within people of the same type and SX first INTP would have a stronger than drive on average.
5w6 or 9w1 sp/so/sx, I think
