Note that the above article has a bunch of other useful information for adult game designers (i.e. most searched for terms, percentage of porn viewers by sex, etc.).
Here's an article from AARP about adult gaming in general.

So, while the percentage of people over 50 that play computer games is lower than younger generations, yeah there are a lot of 50+ peeps that game. And a lot of 50+ peeps that watch porn. So it's not much of a stretch to assume that we don't have at least a few people that are 50+ on this forum, out of nearly 900,000 users.
Heck, we even have a few 50+ people on this site that mod or design adult games! I'm not naming any names though, that's up to them to tell you who they are (or not).
Sure the over 50'ers aren't anywhere near the majority of the users here, if you are looking for which age group is largest, and hence most worth targetting. But that isn't the same as assuming that they are too stupid to know how to use Google to find porn, and by extension, porn games...
Assume = ASS out of U and ME.
BTW, Al Lowe? Who is Al Lowe, you ask?
All Lowe created the porn game Leisure Suit Larry, which is tame by today's standards but was quite controversial for it's time.
He's 72 this year.
