Perhaps the answer lies in an open discussion, as two adults. Personally I think Beagle is right to be concerned esp as Pa had a mailbox isse, which may be resulting from spam occurring as a result of visiting 'dodgy' sites. He may enjoy the hem-hem 'artistic nude' but possibly doesn't understand how scammers and con artists who can get to him online as a result. But breaching this needs an understanding of Pa's perspective - was getting an eyeful considered sinful / shameful in his upbringing? And how easily do you discuss intimate matters with Pa? I agree with others who say it's nobody's business but his own, absolutely, right down to him introducing a new 18year-old Romanian stepmum. However, take the IT out of the equation - would Beagle be right to be concerned if Pa was inviting ladies of negotiable virtue into his house? We can all argue that selling sex is a commodity like any other, but we all also know how much criminality attaches itelf to the trade. And here we have an old gent who is presumably not getting any stronger, may not fully understand the risk, is completely entitled to a satisfying sex life, but may need some gentle support from family to protect him if not 'from his own worst self' then from the predators out there.
