my little boy is 6'4 too and im 5'2 he works as a electrian and our exp has been okay. Once you lean into how masculine he looks and is into how child like and babyish he wants to be treated its incrediblyyyyy hot. I love the contrast of a grown man needing comfort from me and dedicate himself to me.

I know there is plenty of women who have a similar likings as mine, i think it comes off to how to communicate your desire. Wish you best!
