I just looked at a matrimonial site and the difference is that you have self, Son, Daughter, Brother, Son, Sister, Friend and Relative, these all and be added in place of Male and Female.
Here is the link to make the changes, http://www.osdateforum.com/general-osdate-help/drop-down-menu-additions/msg3375/#msg3375
In the link above shows how to remove the gender, adding them is just done the same way in reverse.
The Religion and Community can all be added in the admin area.
If your not sure how to do this, then I would suggest you hire a coder.
