I guess that depends on how private you like to keep your information. The name, address and email address you provide as your administrative and technical contact will be available as a matter of public record. I use my office address to register domain names and I get a few pieces of junk mail a year, some are even fake bills for domain renewal from scammers, but that is another topic.
One thing I would suggest is that the email address you provide for your administrative and/or technical contact is not your primary (personal) email address, as spammers will harvest it. For example, I use a gmail account for this purpose.
If you are unfamiliar, do a WHOIS search on any domain name and you will see what I mean.
