We are "taught" by our mass media (whether porn, or billboard advertising, or whatever) that there are certain things we must prefer...
- smooth twinks
- hairy hunks
- chiseled torsos
- long hair
- tattoos
Personally, I find many of those turn-offs (a small tattoo is fine, but covered in tats? not my thing: even studios I normally collect, I'll pass on, for example, Chris Damned... I'm sure he's a lovely man in person, but I'm no more attracted to his over-tatted body than I am to Roseanne Barr's!)
That doesn't make me judgemental - I've long held that gay "sexual tastes" are a "rainbow of fruity flavors"! 
I like watching twinks have sex - but I like 'em even more as they age into their late 20's! (I hear Helix's Jessie Montgomery is considering a comeback! I'd LOVE to see that! Even if his costars would likely be literally half his age! LOL (No, not quite really half his age - Jessie came to Helix in 2012. If you ASSUME he was 18 then, he's 28 now... but still, that's close enough to 30 for me! LOL)
But can someone please tell me why ALL "daddies" shown in gay porn have to have hairy chests & beards? (one exception: LeGrand Wolf - tho he does have a hairy chest)
As much as "twinks" and "daddies" are the hot thing now, in my youth, the "gay norm" was guys with mustaches and hairy chests! Eww for me, then and now!
Not trying to hijack the conversation tho - I think you're attracted to who you're attracted to by a "matrix" of inputs - some environmental, some biological, some social.
Also, hearkening back to the original post: I do NOT believe homosexuality is caused by a lack of a loving father figure in childhood. While that may be a part, I've known plenty of 100% straight men who had issues with their fathers!
IMHO, more gays had issues with their fathers growing up - not because their fathers were "turning them gay", but because their fathers were uncomfortable with their gay sons! (not having a close relationship to your father didn't make you gay - rather, being gay caused you to have a lesser relationship with your father... and in as much as you were a kid then, that's on your father, not you!)
