It's is always gonna be a gross out subject. If an older guy is hot and younger adult (emphasis on adult) want to play together or much more so be it as adults have a choice on who they want to involve themselves with however I find the idea of calling it dad/son automatically has overtones of incest. Older and younger happens and always will but why the f**k does it have to be called that??
There are many guys who willingly engage in relations that are inter-generational by definition of number of years and many more others who revile at the thought of someone 5-10 or more years touching them. When consenting adults 21+ ( even though legal age in Oz is 18 in every state) then adults do this by choice and if you don't like it don't do it ect.... Personally if a guy meets my needs and 21, age is just a number and all are seen through a prism of ' you make me hot or you do not , good luck on your search'.
If a younger guy wants to interact and it's 'age irrelevant' the way he interacts then he is in with the same chance at 22 as is at 42. If on the other hand a guy calls me daddy or something suggesting that, he is likely to be a troll and all of the few who have done that have been over 25 most nearly 30 which shows that they are full of shite or think miracle 10-12 yr old fathers happen often lol. They all get blocked especially teens after reporting to moderator if they message me for hook up which always end up being Grindr.
My guess is that we have another ill thought naming of a fetish once again that will potentially through the more vulnerable guys (those who live in gay hostile areas) to cop more crap from ignorant homophobes. Go give yourselves and upper cut if you think that dad and son is a good description of people making adult choices. As for pedophiles into underage teens and younger, your day of justice will come, just never soon enough for the victims. As for the stupid people who decide on the naming of this genre, once again please stop sniffing poppers before you write or post about something potentially controversial or you'll will keep coming up with dum ideas which end up stigmatising everyone, including those who only include much much older guys as their objects of affection
