First Mabrook! May ALlah bless ur marriage ameen n make u one another the coolness of each others eyes ameen.:sunny:
Ofcourse u can wait n take it slow. There is nothing wrong wit that. I assume ur a sister so the way u feel is normal, as I have heard similar stories from sisters who felt this way n I don't blame them.
I think wat happens on the wedding night, is wat the husband n wife want, u don't have to follow any rules. Wen Allah makes u husband n wife, u can share anything, incl: letting him know how u feel. InshaAllah he'll understand.
