Pegging advice?

I've only tried it once so far and I've had some trouble. Mostly that since I can't actually feel anything I barely know if I'm doing it right or a good job--everything just feels weird. I mean, if something was off he would say so, but I can't keep a consistent pace (hell even when i masturbate or like, just pretend 😳). And I'm like a foot shorter than him and kind of dainty so like, it's hard to get a good grip on his hips or angle myself well enough from behind. It's af if he's on top but dammit I want to be able to straight up dom! We don't get to fool around with it much since we don't have a place of our own yet, and want to save all the kinky shit for when we've got an apartment (I mean, there are opportunities but they're rare), but is there anything I can do to train myself/practice for next time?
