Dear Holy Yid,
In his Shabbos Shuva Drasha last year, my Rav requested that every member of the Shul install an Internet filter. I immediately realized that his request was the opportunity of a lifetime. I told my wife of the Rav's request, that I plan to comply, and requested her help with the password. My wife has the password to the Internet filter, and should the password be lost, it gets sent to her e-mail address, to which I have no access.
The filter allows most legitimate sites, but sometimes it blocks them. When it's convenient, I have my wife enter the password, I unblock those sites, and close the filter program immediately. Sometimes a relative will e-mail me a link that I can't access due to the filter. I have no problem letting them know that I cannot access the link due to my Internet filter - I am proud to share that fact, and hope that I will inspire someone (regardless of their age or marital status) who has unfiltered Internet to reconsider. Those without a filter should be the ones to feel awkward.
Noorah's point is very well-taken. Having an Internet filter is probably the most important thing you can do for both your spirituality and for your emotional equilibrium.
