Dude, Start with Baby Steps. I think a lot of tradition women, do not like pain involved with sex. So start with oral, maybe slow fingering, pleasure her as much as you can.
Good Luck
As far as i know there are no restrictions, Poojawa baageta dena eka nam maatha ahala thiyenawa, but lamai gana scene eka nam wenna baaa. So wat I suggest is this go me the priest by ur self and if he says like this take the opinion of another priest....Good Luck
